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 Procedures
Awarm-up procedure is recommended at each start-up and is
essential at ambient temperatures below +40°F (4°C).
The prime mover should be run at its lowest recommended
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, forward and reverse, several times
to prime all lines with warm hydraulic oil, and to circulate gear
lubricant through the planetary gear sets.
WARNING
CAUTION
!
Failure to properly warm up the winch, particularly
under low ambient temperature conditions, may result
in temporary brake slippage due to high back pres-
sures attempting to release the brake, which could
result in property damage, severe personal injury or
death.
8. Recommended Planetary Gear Oil
Field experience, supported by extensive engineering
tests, indicates the use of the proper planetary gear oil
is essential to reliable and safe operation of the brake
clutch and obtaining long gear train life.
WARNING
!
Failure to use the proper type and viscosity of plane-
tary gear oil may contribute to intermittent brake clutch
slippage which could result in property damage,
severe personal injury or death. Some gear lubricants
contain large amounts of EP (extreme pressure) and
anti-friction additives which may contribute to brake

clutch slippage and damage to brake friction discs or
seals. Oil viscosity with regard to ambient temperature
is also 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 tempera-
ture.
For simplicity, BRADEN has listed one (1) readily avail-
able product in each temperature range which has
been tested and found to meet our specifications. This
is not to say that other lubricant brands would not per-
form equally as well.
If the following lubricant brands are not available in
your area, make certain your lubricant vendor supplies
you with oil that is equivalent to those products listed
below.

BRADEN planetary winches are factory filled with
Texaco Meropa 150 or equivalent API GL-2/3 gear oil.
9. Inspection
In compliance with ANSI specification number
B30.5c1987 and API Recommended Practice RP 2D
section 3, we recommend that the winch be disassem-
bled for a thorough inspection of all wear items every
2,000 hours of operation or twelve (12) months,
whichever occurs first.
