LUBRICATION 1400A OPERATOR’S MANUAL
Hoist Brake Oil
To check the hoist brake oil, remove the vent/fill plug and
visually inspect the level (Figure 5-3). The fluid should be
level with the bottom of the vent/fill hole. If more fluid is
needed, use National Crane hydraulic oil.
.
Hoist Gearbox Oil
To check the hoist gearbox oil level:
• Rotate the drum until the oil fill/drain plug is level with the
oil level/fill inspection hole (Figure 5-4).
• Remove the oil fill/drain plug and visually inspect the
level. The oil should be level with the bottom of the
inspection hole. If more oil is needed, add SAE 90 EP
gear lube.
NOTE: Hoist gear and brake lubricants are satisfactory for
operation in temperatures from -10°F to +110°F (-
23°C to 43°C). For operation outside this range,
contact Manitowoc Crane Care for
recommendations.
.
1400A Hydraulic Oil Reservoir Level
The hydraulic oil reservoir has a sight gauge located on the
side of the reservoir (Figure 5-5). The oil in the hydraulic
reservoir is sufficient when the level is between the upper
and lower marks on the sight gauge with the crane parked on
a level surface in the transport position and the oil cold.
If the oil level is to low, add the recommended hydraulic oil
until the oil level is even with the upper mark. If the oil level is
high, drain oil until the oil level is even with the upper mark.
DANGER
Do not use EP type gear lubes in the brake section. This
may prevent proper operation and cause the load to fall
resulting in serious injury or death.
