Hydraulic Hoses
Inspect all hydraulic hoses for leaks, nicks, cuts, chafing, and bulges. Replace damaged hoses as soon as possible. Inspect all fittings for leaks. Repair any leaks immediately.
Hydraulic Reservoir
Check fluid level. See “Lubrication Equivalency Chart” on page A-2. Add fluid if necessary.
Lift Chains
Check adjustment. Inspect for excessive stretch or wear (tool P/N 950-350/CG) Lubricate. See “Chain Maintenance” on page 4-8.
Lubrication
Lubricate all grease points. Lubricate the load wheels. Lubricate all pivoting shafts on the control arm with spray lube. Lubricate fork positioning locks.
Mast
Examine mast bearings. Inspect rails for abnormal wear, metal flakes, or shavings. Wipe old grease off mast uprights and apply new grease.
Motors
AC (traction) - Check the cable lugs to make sure they are tight to the terminal studs. The outside nut should be torqued to the values listed on page 7-61. Replace any cable that shows signs of excessive heat. Check sensor wires for sound connection and condition. DC (lift) - Visually inspect brushes for excessive heat (discoloration of the pigtails). If excessive heat is evident, inspect the armature circuit for loose connections. Check condition of commutator per photos on page 5-5. Find the shortest brush in the holder. Remove the brush and check overall dimension as per the chart on page 7-60. Inspect the brush for even wear over the full surface of the brush. If the brush is not contacting the complete surface, replace the brushes. Inspect the brush rigging for damage or loose brush holders. Make sure that the connections on the brush leads are tight. Check brush spring tension per the chart on page 7-60. Blow out the inside of the motor with compressed air. Check the cable lugs to make sure they are tight to the terminal studs. Both the inside and outside nut should be torqued to the values listed on page 7-61. Replace any cable that shows signs of excessive heat. See “DC Motors, General” on page 7-59.
