Compound Bow Maintenance Schedule — What to Do and When
Most compound bow problems don't announce themselves. They build quietly — a cam axle drying out over hundreds of shots, a string slowly losing its wax protection, a cable slide developing drag that adds a fraction of a pound to every draw. By the time you notice something is wrong, the wear has already been happening for weeks or months.
A compound bow maintenance schedule solves this by turning reactive care into proactive care. Instead of waiting for a squeak or an inconsistent group to tell you something needs attention, you work through a routine at set intervals that catches problems before they affect your shooting — or your equipment.
This article breaks down exactly what to do and when — from the 60-second check before every session to the annual press service that keeps your bow safe and properly tuned.
Quick answer:
Inspect strings and cams before every session. Wax strings every 2–3 weeks during regular shooting. Lubricate cam axles and cable slide rails with silicone oil every 1,500–2,000 shots. Get a professional press inspection once per year. Replace strings and cables every 2–3 years or at the first sign of visible wear.
Why a Maintenance Schedule Matters More Than Occasional Care
The difference between occasional bow maintenance and a scheduled routine is the difference between reactive and preventive care. Archers who maintain their bows when something feels wrong are already behind — the problem started before they noticed it.
A schedule removes the guesswork. You don't have to decide whether the string looks dry enough to wax or whether it's been long enough since you last oiled the axles. You follow the intervals, and the bow stays in the condition it should be in rather than gradually drifting out of it.
There's a practical accuracy benefit too. Friction buildup at cam axles introduces draw cycle variation that is almost impossible to distinguish from form inconsistency. Archers spend hours working on their technique trying to fix groups that are actually a lubrication problem. A proper schedule eliminates that variable entirely.

Before Every Session — The 60-Second Check
The pre-session inspection takes less than a minute and is the single most important safety habit in archery. A compound bow stores enormous energy under tension — a compromised string or cracked limb that goes unnoticed can fail catastrophically during a shot.
Strings and cables
Run your eye along the full length of the bowstring and cables. You are looking for fraying of the outer fibers, broken individual strands, or separation of the serving at the nocking point or cam grooves. Any of these is a stop-shooting situation. Do not shoot a bow with a visibly damaged string.
Cam rotation
Spin each cam by hand with the bow undrawn. They should rotate freely with zero resistance or grinding. A rough or gritty cam rotation means the axle is either dry and needs lubrication, or there is debris in the cam system that needs to be cleaned out before shooting.
Hardware
Give your sight and arrow rest a quick check for tightness. Vibration from shooting gradually works fasteners loose — a sight that shifts by even half a millimeter between sessions will shift your point of impact significantly at distance.
Limbs
A quick visual scan of both limbs for any cracks, delamination, or unusual marks. This takes five seconds. If you see anything that wasn't there before, take the bow to a shop before shooting again.
Every 2–3 Weeks — String Wax and Light Cleaning
During any active shooting period — regular practice, pre-season prep, hunting season — bowstring wax should be applied every two to three weeks. In harsh conditions (dust, humidity, cold) or with heavy shooting volume, apply more frequently.
How to wax a bowstring correctly
Apply a small amount of bowstring wax directly to the string fibers along the full length of the string — not to the serving at the nocking point. Work the wax into the strands with your fingers, then use a piece of leather or a waxing tool to rub it back and forth briskly. The friction generates heat that drives the wax deeper into the fiber structure. Wipe away any excess that balls up on the surface. The finished string should feel slightly tacky — not wet, not heavily coated.
Never use oil on bowstrings or cables. Oil breaks down synthetic bowstring fiber structure and dramatically accelerates wear. Strings require wax only.
Light cleaning
Every few weeks, wipe down the cam grooves, cable slide rail, and riser with a clean lint-free cloth. You are removing the accumulated dust and grit that works into contact zones between sessions. This is especially important to do before applying any lubrication — lubricating over grit suspends the abrasive particles in the oil film and accelerates wear rather than preventing it.
Limb bolts
Give both limb bolts a check for tightness. They should be at manufacturer-specified torque. Bolts that have worked loose will change your draw weight subtly and, if left long enough, can affect cam timing and draw cycle consistency.
Every 1,500–2,000 Shots — Lubrication
This is the most commonly missed interval in compound bow maintenance — and the one with the most direct impact on performance. At 100 shots per session that's roughly 15–20 sessions, or about one hunting season worth of shooting. Many archers go years without lubricating their cam axles.
The 1,500–2,000 shot interval is based on manufacturer guidance from major bow brands including Hoyt. It represents the point at which friction buildup at axle contact points begins to affect draw cycle consistency in measurable ways — before any audible warning signs appear.
Cam axles — the most critical lubrication point
If your bow uses cams that rotate on open bushings rather than sealed bearings, the axle pin needs periodic lubrication. Apply a small amount of GNP Defend Silicone Oil directly to each axle pin where it enters the cam. One small application per side is sufficient. Always clean the axle area first with a dry cloth before applying fresh lubrication.
If your bow uses sealed cam bearings — which most bows built in the last decade do — skip this step entirely. Sealed bearings are factory-packed with grease and cannot be lubricated externally. If sealed bearings feel rough or gritty, that is a press service or replacement issue, not a lubrication issue.
Cable slide rail — the most overlooked lubrication point
The cable slide moves laterally under cable pressure every single draw. A dry slide adds drag to the draw cycle that is almost imperceptible at first but accumulates over thousands of shots. Apply a light, even coat of silicone oil along the full length of the cable guard rail and wipe away any excess. This single step has a noticeable effect on draw smoothness and cable wear.
Adverse conditions — lubricate sooner
The 1,500–2,000 shot interval assumes normal shooting conditions — indoor range or dry outdoor range. If you have been hunting in rain, mud, dust, or extreme cold, inspect and re-lubricate regardless of shot count. Moisture displaces lubrication from axle surfaces and creates conditions for corrosion. Grit in cam grooves acts as an abrasive that accelerates wear many times faster than friction alone.

Once Per Year — Professional Press Inspection
Annual professional service is the one maintenance task that cannot be done at home without specialized equipment. A bow press is required to safely take the bow off tension for full inspection, string and cable replacement, and timing adjustments. Attempting these without a press is dangerous — the stored energy in compound bow limbs is significant.
What the annual service covers
A professional archery technician will check draw weight against your specified setting, inspect cam timing and synchronization, assess string and cable condition and replace them if necessary, check limb condition for any developing cracks or delamination, verify axle condition and bearing function, and inspect all hardware for wear or looseness. This is the service that catches the problems routine maintenance cannot — the ones that develop slowly inside the bow's mechanical system.
When to go more frequently
High-volume shooters — anyone putting 5,000 or more shots through a bow in a year — should consider a press inspection every six months. Competition archers who depend on precise cam timing and consistent draw weights benefit from more frequent professional attention. Hunters who shoot in demanding conditions should also consider a pre-season service in addition to the annual inspection.
Every 2–3 Years — String and Cable Replacement
Strings and cables are wear items. They don't last indefinitely no matter how well you maintain them. The fibers degrade with use, stretch under repeated tension, and accumulate microscopic damage at their contact points with cam grooves and cable slides.
Most manufacturers recommend replacement every two to three years under regular shooting — or sooner if you notice fraying, broken strands, serving separation, or any change in draw cycle feel that can't be explained by tuning. High-volume shooters may need replacement closer to every 1,500–2,500 shots.
When replacing strings and cables, replace the complete set at the same time. Mismatched string and cable stretch characteristics affect cam timing and draw cycle consistency. A new string on old cables, or vice versa, introduces variables that are difficult to tune out.
Seasonal Maintenance — Hunters vs Year-Round Archers
The base schedule above applies to any archer shooting regularly. Hunters and year-round target archers have slightly different priorities at different times of year.
For hunters
The key maintenance windows are pre-season (typically late summer) and post-season (after the final hunt). Pre-season is when you should confirm the bow is fully tuned, strings and cables are in good condition, and lubrication is fresh. Post-season is when you clean the bow thoroughly, apply fresh lubrication to axle points for storage, wax the strings, and store it correctly for the off-season.
After any hunt in wet or dirty conditions — rain, mud, heavy dew — inspect and re-lubricate immediately rather than waiting for the scheduled interval. Moisture and grit in cam systems during storage cause more damage than they do during active use.
For year-round archers
Year-round shooters can follow the base schedule more strictly — the intervals are consistent because shooting is consistent. The one additional consideration is temperature. If you shoot outdoors through winter, silicone oil is particularly important because it maintains consistent viscosity in the cold, unlike petroleum-based lubricants that thicken and provide reduced protection at low temperatures.
Signs Your Maintenance Schedule Has Slipped
Even with the best intentions, maintenance sometimes falls behind. These signs tell you the bow needs immediate attention before the next session:
- Audible squeaking or creaking during the draw cycle — almost always dry axles or a dry cable slide
- Gritty cam rotation when spinning cams by hand — dry or contaminated axle surface
- Draw cycle that feels heavier or more inconsistent than usual without any adjustment — accumulated friction
- Dry, fuzzy, or brittle-feeling string — over-due for waxing
- Peep sight that rotates during the draw — string may have lost its set or serving is wearing
- Groups that have opened up without any change in form — often a maintenance issue before it's a technique issue
- Surface rust on axle pins after moisture exposure — lubrication has been displaced and needs immediate replacement

Frequently Asked Questions
How often should I maintain my compound bow?
The full schedule has four tiers: inspect strings and cams before every session; wax strings and do light cleaning every 2–3 weeks; lubricate cam axles and cable slides with silicone oil every 1,500–2,000 shots; and get a professional press inspection once per year. Most of the routine is visual inspection — the actual hands-on maintenance happens at the 2–3 week and 1,500–2,000 shot intervals.
How often should I wax my compound bow string?
Every 2–3 weeks during regular shooting is the standard recommendation. In harsh conditions — outdoor shooting in dust, humidity, or cold — apply more frequently. You can also gauge it by feel: a string that feels dry or looks fuzzy needs wax. A string that feels slightly tacky is properly conditioned.
How often do you oil a compound bow?
Cam axles and cable slide rails should be lubricated every 1,500–2,000 shots. At 100 shots per session that's roughly 15–20 sessions. After shooting in rain, mud, or heavy dust, inspect and re-lubricate sooner regardless of shot count. Always use silicone oil — never WD-40 or petroleum-based oils.
How often should compound bow strings be replaced?
Every 2–3 years under regular use, or sooner if you notice fraying, broken strands, serving separation, or any change in draw cycle feel. High-volume shooters may need replacement every 1,500–2,500 shots. Always replace the full string and cable set at the same time — mismatched wear characteristics affect cam timing.
Do I need to take my compound bow to a shop every year?
Yes — an annual professional press inspection is recommended for all compound bows. A bow press is required to safely take the bow off tension for full inspection, cam timing verification, and string replacement. This is not safely done at home without proper equipment. The annual service catches problems that routine maintenance cannot identify.
Does the maintenance schedule change for hunting vs target archery?
The base schedule is the same. Hunters add two specific windows — a full pre-season inspection and lubrication before the season starts, and a post-season clean, lubricate, and store routine after the final hunt. Hunters also need to inspect and re-lubricate after any session in wet or dirty conditions, regardless of shot count.
How do I know if my compound bow needs maintenance right now?
Check for these signs: gritty or rough cam rotation by hand, audible squeaking or creaking during the draw, inconsistent draw feel without any adjustment, dry or brittle string, groups that have opened up without any form change, or visible surface rust on axle pins. Any of these means maintenance is overdue.
The Maintenance Schedule in Summary
Every session — inspect strings, cams, and hardware. Every 2–3 weeks — wax strings, clean cam grooves and cable slide. Every 1,500–2,000 shots — lubricate cam axles and cable slide rail with silicone oil. Once per year — professional press inspection. Every 2–3 years — replace strings and cables.
That's the complete routine. It costs very little time per session and a small amount of money per year. What it returns is a bow that draws consistently, shoots accurately, and lasts for a decade or more rather than degrading quietly over a few seasons.
