2. Procedure for Gear Oil Exchange:
Gear Oil for exchange should be the same type and brand. Do not mix different oil.
(1) Lower hook as well as any load to the ground.
(2) Set face of refuel port and drain port perpendicular to horizontal level. (Refer to a figure below)
(3) Suspend hydraulic pump.
Change oil after lowering Hook as well as any load to the ground and halt whole machine.
Otherwise, accidental fall of load and/or unforeseeable motion may cause injury.
Motor, after operation, may be extremely hot. Allow oil to cool before change.
Otherwise, a gush of hot oil may cause burns.
(4) Dump gear oil
Remove plugs of both refuel and drain for exchange.
Or, remove refuel plug for refilling.
(5) Pour 0.2 gal (0.75 liter) of gear oil from the port, or to the level of refuel port for refilling.
(6) Tighten plugs to ports. Always use seal tapes when tighten plugs.
3. Maintenance
Perform daily maintenance and inspection of items below before starting motor, CH01A.
Except abnormal noise check of item (3) below, always start maintenance and inspection only after
lowering hook as well as any load to the ground and halt this winch and hydraulic pump. Maintenance
and/or inspection during operation may cause injury or burns.
(1) Oil leakage (Hydraulic oil and Gear oil)
(2) Loose bolts.
(3) Abnormal noise.
Drum, after operation, may be extremely hot. Use a thermometer for measurement of temperature and
never touch drum and/or rear flange to prevent burns.
(4) Extraordinary temperature raise of drum and/or rear flange body.
[Maximum allowable temperature under uninterrupted services is 176°F (80°C)]
(5) Assure that gear oil has been correctly changed, periodically.
