Recommended Oil Change Information - BRADEN PD12C Series Installation Maintenance And Service Manual

2. OIL CHANGE
The gear oil should be changed after the fi rst
one hundred (100) hours of operation, then every 1,000
operating hours or six (6) months, whichever occurs
fi rst. 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 personal
injury or death.
The gear oil should also be changed whenever
the ambient temperature changes signifi cantly and an
oil from a different temperature range would be more
appropriate. Oil viscosity with regard to ambient tem-
perature 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
hoist 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 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 plug, clean in solvent and reinstall.
Do not paint over the vent or replace with a solid plug.
4. HYDRAULIC SYSTEM
The original fi lter element should be replaced
after the fi rst fi fty (50) hours of operation, then every
500 operating hours or three (3) months, or in accor-
dance with the equipment manufacturer's recommen-
dations.
5. WIRE ROPE
Inspect entire length of wire rope according to
wire rope manufacturers recommendations.
6. MOUNTING BOLTS
Tighten all hoist base mounting bolts to recom-
mended torque after the fi rst one hundred (100) hours
of operation, then every 1000 operating hours or six (6)
months, whichever occurs fi rst.
Failure to properly warm up the hoist, particularly un-
der 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.
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
recommended RPM with the hydraulic hoist control
valve in neutral allowing suffi cient time to warm up
the system. The hoist should then be operated at low
speeds, raise and lower, several times to prime all lines
with warm hydraulic oil, and to circulate gear lubricant
through the planetary gear sets.
8. INSPECTION
A. Bearings and Gears – Refer to
DISASSEMBLY OF Hoist, page 15; and
PLANET CARRIER SERVICE, page 20.
B. Brake Cylinder – Refer to MOTOR
SUPPORT – BRAKE CYLINDER SERVICE,
pages 22 and 23.
C. Brake Clutch – Refer to BRAKE CLUTCH
SERVICE, page 26.
Failure to use the proper type and viscosity of plan-
etary gear oil may contribute to intermittent brake
clutch slippage which could result in property dam-
age, severe personal injury or death. Some gear lu-
bricants contain large amounts of EP (extreme pres-
sure) 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 viscos-
ity used in your hoist is correct for your prevailing
ambient temperature.
9. RECOMMENDED PLANETARY GEAR OIL
Use of the proper planetary gear oil is essential
to reliable and safe operation of the brake clutch and
obtaining long gear train life.
For simplicity, BRADEN has listed one (1) read-
ily available product in each temperature range which
has been tested and found to meet our specifi cations.
