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 150
to 250
Á
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 FULL mark on the dipstick, using the transmission fluid
recommended by HYUNDAI.

heck the planned maintenance interval (operating hours) or the condition of the oil to
determine if the transmission fluid needs to be changed.
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
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
Lubricate the entire length of the mast rail lift and carriage chains with HYUNDAI chain and cable
lube.

Hydraulic fluid and filter change
Drain and replace the hydraulic sump fluid every 2000 operating hours.(Severe service or adverse
conditions may require more frequent fluid change). 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
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.
