HOW TO MAKE THE CHECKS WITH THE
ENGINE STOPPED
Put the lift truck on a level surface. Lower the carriage and
forks, stop the engine and apply the parking brake. Open
the hood and check for leaks and conditions that are not
normal. Clean any oil or fuel spills. Make sure that lint,
dust, paper and other materials are removed from the en-
gine compartment.
Hydraulic System Oil (See FIGURE 8.)
WARNING
At operating temperature the hydraulic oil is HOT. Do
not permit the oil to contact the skin and cause a
burn.
CAUTION
Do not permit dirt to enter the hydraulic system when
the oil level is checked or the filter is changed.
Never operate the pump without oil in the hydraulic
system. The operation of the hydraulic pump without
oil will damage the pump.
Check the hydraulic oil level when the oil is at operating
temperature, the carriage is lowered and the engine is
stopped. Add hydraulic oil only as needed. If more hydrau-
lic oil is added than the FULL level, the hydraulic oil will
leak from the breather during operation. The breather for
the S135--155XL units is
under
the top of the frame near
the filter.
Check the hydraulic system for leaks and damaged or
loose components.
