BATTERY
Keep the battery case and the battery
compartment clean and painted. Leaks and
corrosion from the battery can cause a
malfunction in the electrical controls of the lift
truck. Use a water and soda solution to clean the
battery and the battery compartment. Keep the
top of the battery clean, dry, and free of
corrosion. Refer to APPENDIX A: INDUSTRIAL
BATTERY for more detailed procedures for
cleaning the battery.
Where applicable, check the level of the
electrolyte on all cells. Refer to the instructions
from the manufacturer of your battery for the
correct operating level of the electrolyte.
HYDRAULIC SYSTEM
WARNING
w
The operating temperature of the hydraulic
oil is 90
o
F - 160
o
F.
w
Disconnect the battery while servicing.
w
Before disconnecting any hydraulic lines,
relieve the pressure in the lines.
w
Hydraulic oil under pressure can be
injected into the skin. Never check for
leaks by putting hands on a hydraulic line
under pressure.
CAUTION
w
DO NOT permit dirt to enter the hydraulic
system when checking the oil level.
w
Never operate the steer or lift pump
without oil in the hydraulic system. Doing
so will damage the pump.
1.
Lower the carriage and tilt the mast fully
forward. Check the hydraulic oil level with the
dipstick. Make sure the temperature of the oil
is at least 90
o
F.
2.
If the oil level is low, carefully check for leaks
and damaged or loose components.
LIFT CHAINS
WARNING
DO NOT work under a raised carriage. Lower
the carriage and forks to the ground or use a
suitable locking device to prevent the carriage
and rails from lowering when performing
maintenance on the lift chains.
1. Visually inspect the lift chains for cracks or
broken links and pins. Check for corrosion or
worn holes in the links. As the links and pins
wear, the chain will become longer.
2. Use a chain scale to check the lift chains. If a
chain scale is not available, measure 20 links
of chain. Replace the chain if the length of 20
links of the worn chain is more than 15.45”.
WARNING
w
Replace a worn chain - DO NOT try to
repair it.
w
If one chain in a pair has a defect, replace
both chains.
3. Inspect the chain anchors and pins. Replace
the chain anchors if there are cracks or worn
holes. Replace chain anchor pins that are
worn or damaged. Replace broken or missing
cotter pins.
4. Check the lift chains for dryness. If needed,
lubricate them as described in the 350-HOUR
/ 60-DAY INSPECTION section.
