3. Vent Plug
The vent plug is located directly above the winch mo-
tor near the brake release port. It is important to keep
this vent clean and unobstructed. Whenever gear oil is
changed, remove vent plug, clean in solvent and rein-
stall.
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 50 hours of operation, then every 500 operat
-
ing hours or three months, or in accordance with the
equipment manufacturer’s recommendations.
5. Wire Rope
Inspect entire length of wire rope according to wire
rope manufacturer’s recommendations.
6. Mounting Bolts
Tighten all winch base mounting bolts to recommended
torque after the first one hundred (100) hours of opera
-
tion, then every 1,000 operating hours or six months,
whichever occurs first.
7. Warm-up Procedures
A warm-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 recom-
mended 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.
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
and obtaining long gear train life.
For simplicity, we have listed one readily available
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 perform
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
on following page.
CH330/CH400 planetary winches are factory filled with
Texaco Meropa 150 or equivalent.
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 12 months, whichever oc-
curs first.
Failure to properly warm up the winch, particularly un-
der low ambient temperature conditions, may result in
temporary brake slippage due to high back pressures
attempting to release the brake, which could result in
property damage, severe personal injury, or death.
Failure to use the proper type and viscosity of planetary
gear oil may contribute to intermittent brake clutch slip-
page which could result in property damage, severe
personal injury, or death. Some gear lubricants contain
large amounts of extreme pressure (EP) and antifric-
tion additives which may contribute to brake slippage
and damage to brake friction discs or seals. Oil viscos-
ity with regard to ambient temperature is also critical to
reliable brake operation. Our tests indicate that exces-
sively heavy or thick gear oil may contribute to intermit-
tent brake slippage. Make certain that the gear oil vis-
cosity used in your winch is correct for your prevailing
ambient temperature.
