Engine oil and filter
Locate the engine oil dipstick. Pull the dipstick out, wipe it with a clean wiper, and reinsert it fully
into the dipstick tube. Remove the dipstick and check oil level.
It is normal to add some oil between oil changes. Keep the oil level between the Full and Low mark on
the dipstick by adding oil as required. Do not overfill. Use the correct oil as specified under lubricant
specification.
It is recommended to:
Â
Drain and replace the engine crankcase oil every 50 to 250 operating hours(Depending on
application).
Â
Replace the LPG engine oil filter every 500 hours, diesel engine every 250 hours.
Â
Remove the oil pan drain plug to drain old oil after the truck has been in operation and the engine(oil)
is operating temperature.

ngine oil at operating temperature is hot and can cause burns. Beware of splashing oil.
Â
Carefully check for leaks after changing oil and installing new filter.
The time interval for changing engine oil depends upon your application and operating
conditions. To determine the correct schedule for your truck, it is suggested that you
periodically submit engine oil samples to a commercial laboratory for analysis of the
condition of the oil.
OIL PERFORMANCE DESIGNATION: To help achieve proper engine performance and durability, use
only engine lubricating oils of the proper quality. For LPG and diesel engines, HYUNDAI recommends
that you use motor oil that meets API service classification CD, CC/SG, SF and API CH4 SAE 15W-40
for diesel engines, gas engines use API SG, SAE 10W-30 oil or better.
Hydraulic sump tank
Check the hydraulic sump tank fluid level. Correct fluid level is important for proper system operation.
Low fluid level can cause pump damage. Over filling can cause loss of fluid or lift system malfunction.
Hydraulic fluid expands as its temperature rises. Therefore, it is preferable to check the fluid level at
operating temperature(after approximately 30 minutes of truck operation). To check the fluid level, first
park the truck on a level surface and apply the parking brake.
Put the mast in a vertical position and lower the fork carriage fully down. Pull the dipstick out, (attached
to the sump breather) wipe it with a clean wiper, and reinsert it. Remove dipstick and check oil level.
Keep the oil level above the LOW mark on the dipstick by adding recommended hydraulic fluid only, as
required. Do not overfill.
Check the condition of the hydraulic fluid(age, color or clarity, contamination). Change (replace) the oil
as necessary.

Your lift truck cooling system is filled with a factory installed solution of 50% water and 50%
permanent-type antifreeze containing rust and corrosion inhibitors. You should leave the
solution in year around. Plain water may be used in an emergency, but replace it with the
specified coolant as soon as possible to avoid damage to the system. Do not use alcohol or
methanol antifreeze.
