Transmission fluid check
Transmission fluid check
To check the transmission fluid locate the dipstick. The dipstick is located on the driver's left
hand side under the floor plate near the transmission valve. Before checking, run the engine until
the unit is at operating temperature. This is important since transmission oil temperature should
be minimum of 65˚C (150˚F) to 120˚C (250˚F) maximum, the engine should also be at operating
temperature. Apply the parking brake.
With the engine operating at idle and the transmission in NEUTRAL, and the parking brake set,
check the fluid on the dipstick. Fill, if necessary, to the Normal zone on the dipstick, using the
transmission fluid recommended by HYUNDAI.
Check the planned maintenance interval (operating hours) or the condition of the oil to

Truck chassis inspection and lubrication
Truck chassis inspection and lubrication
Lubrication and inspection of truck chassis components, including steering wheels, steering axle
linkage, steering cylinder, and wheel bearings are easier if the truck is raised and blocked up
under the frame. Refer to your service manual for additional information on machine blocking
and jacking. Also refer to your service manual for the location of grease fittings.
Inspect the steering cylinder piston rods, seals, and fasteners for damage, leaks, and looseness.
Lubricate the steering axle linkage rod ends and linkage pivot points. Be sure to clean the
grease fittings before lubricating, and remove the excess grease from all points after lubricating.
Lubricate miscellaneous linkage as needed.
Mast and tilt cylinder lubrication
Mast and tilt cylinder lubrication
Clean the fittings and lubricate the tilt cylinder rod end bushings (forward end) and both the base
rod-end bushings (rear end). Clean and lubricate the mast trunnion bushings.
Lift chains
Lift chains
Lubricate the entire length of the mast rail lift and carriage chains with HYUNDAI chain and cable
lube.

Hydraulic fluid and filter change
Hydraulic fluid and filter change
Drain and change the hydraulic sump fluid every 2000 or 5000 operating hours. (Severe service
or adverse conditions may require more frequent fluid change). Please to the page 7-9 for service
interval. Replace the hydraulic oil filter element at every oil change. Remove, clean, and reinstall
the hydraulic and steer system suction line screens at first PM and every 500 hours thereafter.
Check for leaks after installation of the filter. Also, check that the hydraulic line connections at the
filter adapter are tightened correctly.
Sump tank breather maintenance and inspection
Sump tank breather maintenance and inspection
Remove the sump tank fill cap/breather and inspect for excessive (obvious) contamination and
damage. Replace the fill cap/breather, per recommended PM schedule or as required by
operating conditions.
