987 and Amerian 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 operating hours or three (3) months, whichever occurs first. To check the oil level,
remove the pluglocated in the drum support. The oil should be level with the bottom of this opening. If additional oil in need, refer
to " Recommended Planetary Gear Oil".
2. Oil Change
The gear oil should be change after the first one hundred (100) hours of operation, then every 1000 operating 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 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 personal 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 viscosity 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 intermittent brake clutch slippage. Make certain that the gear oil
viscosity 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 winch could result in property damage, severe personal 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 unobstructed. Whenever gear oil
is changed, remove vent pulg, 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 operating 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.
6.Mounting Bolts
Tighten all winch base mounting bolts to recommended torque after the first one hundred (100) hours of operation, then every 1000 operating
hours or six (6) months, whichever occurs first.
7. Warm-up Procdures
A warm-up procedure is recommended at each start-up and is essential at ambient temperature below +40°F (4°C).
The prime mover should be run at its lowest tecommended RPM with the hydraulic winch control valve in neutral allowing sufficient time to
warm up the system. The winch should then be operated at low speeds, froward and reverse, several times to p
