PERIODIC MAINTENANCE CHECKS
Never operate the Liftgate if parts are loose or missing.
WARNING
NOTE: Make sure vehicle is parked on level ground while performing the
maintenance checks.
Quarterly or 1250 Cycles (whichever occurs fi rst)
Semi-annually or 2500 Cycles (whichever occurs fi rst)
Visually check the platform hinge pins for excessive wear and broken welds. See PARTS
BREAKDOWN section for replacement parts. Also, do the Quarterly or 1250 Cycles
maintenance checks.
Check the hydraulic fl uid level in the pump reservoir. Refer to the CHECKING HYDRAULIC
FLUID procedure in the PERIODIC MAINTENANCE section.
If hydraulic fl uid appears contaminated, refer to the CHANGING HYDRAULIC FLUID
procedure in the PERIODIC MAINTENANCE section.
Keep track of the grade of hydraulic fl uid in the pump reservoir and never mix two different
grades of fl uid.
Check all hoses and fi ttings for chafi ng and fl uid leaks. Tighten loose fi ttings or replace
parts as required.
Check electrical wiring for chafi ng and make sure wiring connections are tight and free of
corrosion. Use dielectric grease to protect electrical connections.
Check that all WARNING and instruction decals are in place. Also, make sure decals are
legible, clean and undamaged.
Check that all bolts, nuts, and roll pins are in place. Make sure roll pins protrude evenly
from both sides of hinge pin collar. Replace fasteners and roll pins if necessary.
!
Check for rust and oily surfaces on Liftgate. If there is rust or oil on Liftgate, clean it off.
Touch up the paint or galvanized fi nish where bare metal is showing. MAXON recommends
using the aluminum primer touchup paint or cold galvanize spray for galvanized fi nish.
Damaged cylinder seals and contaminated hydraulic fl uid can result from paint-
ing the polished portion of the cylinder rod. To prevent damage, protect the
exposed polished portion of the cylinder rod while painting.
CAUTION
Pump EP chassis grease in each lube fi tting on the cylinders and arms until grease
starts oozing from ends of the bearings. The lubrication diagram on the PERIODIC
MAINTENANCE CHECKLIST SHEET shows where to fi nd the lube fi ttings. Wipe off
excess grease with a clean lint-free cloth.
