Preventive Maintenance - BRADEN CH SERIES Installation Maintenance And Service Manual

A regular program of preventive maintenance for your planetary winch is strongly recommended to minimize the need
for emergency servicing and promote safe, reliable winch operation.
Field experience, supported by engineering tests, indicate the three (3) service procedures listed below are the MOST
critical to safe, reliable winch operation and must be observed.
• Regular Gear Oil Changes – every 1000 hours or six (6) months
• Use of Proper Gear Oil – recommended type for prevailing ambient temperature
• Annual Disassembly and Inspection of All Wear Items – in compliance with American National Standards Institute
(ANSI) specification B30.5c 1987 and American Petroleum Institute (API) recommended practice RP
2D section 3.
The following minimum service intervals are specified
for operating hours of the prime mover.
1. Oil Level
The gear oil level should be checked every 500 oper-
ating hours or three (3) months, whichever occurs first.
To check the oil level, remove the plug located in the
drum support. The oil should be level with the bottom
of this opening. If additional oil in needed, refer to
"Recommended Planetary Gear Oil".
2. Oil Change
The gear oil should be changed after the first one hun-
dred (100) hours of operation, then every 1,000 oper-

ating hours or six (6) months, whichever occurs first.
The gear oil must be changed to remove wear particles
that impede the reliable and safe operation of the
brake clutch and erode bearings, gears and seals.
Failure to change gear oil at these suggested minimum
intervals may contribute to intermittent brake slippage
which could result in property damage, severe person-
al injury or death.
The gear oil should also be changed whenever the ambient
temperature changes significantly and an oil from a different
temperature range would be more appropriate. Oil vis-
cosity with regard to ambient temperature is critical to
reliable brake clutch operation. Our tests indicate that
excessively heavy or thick gear oil may contribute to intermit-
tent brake clutch slippage. Make certain that the gear oil vis-
cosity used in your winch is correct for your prevailing ambient
temperature. Failure to use the proper type and viscosity of
planetary gear oil may contribute to brake clutch slippage
which could result in property damage, severe person-
al injury or death. Refer to "Recommended Planetary Gear
Oil" for additional information.
3. Vent Plug
The vent plug is located in the drum support as shown.
It is very important to keep this vent clean and unob-
structed. Whenever gear oil is changed, remove vent
plug, clean in solvent and reinstall.
Do not paint over the vent or replace with a solid plug.
4. Hydraulic System
The original filter element should be replaced after the
first fifty (50) hours of operation, then every 500 oper-
ating hours or three (3) months, or in accordance with
the equipment manufacturer's recommendations.
5. Wire Rope
Inspect entire length of wire rope according to wire
rope manufacturers recommendations.
