Thoroughly clean the machine. In particular, be careful to clean the filler caps, grease fittings and the
area around the dipsticks. Be careful not to let any dirt or dust into the system.
Always use HYUNDAI Forklift genuine parts for replacement.
Always use the grades of grease and oil recommended by HYUNDAI Forklift.
Choose the viscosity specified for the ambient temperature.
Always use pure oil or grease, and be sure to use clean containers.
When checking or changing the oil, do it in a place free of dust, and prevent any dirt from getting into
the oil.
Before draining the oil, warm it up to a temperature of 30 to 40 C.
After replacing oil, filter element or strainer, bleed the air from circuit.
When the strainer is located in the oil filler, the strainer must not be removed while adding oil.
When changing the oil filter, check the drained oil and filter for any signs of excessive metal particles
or other foreign materials.
When removing parts containing O-ring, gaskets or seals, clean the mounting surface and replace
with new sealing parts.
After injecting grease, always wipe off the oil grease that was forced out.
Do not handle electrical equipment while wearing wet places, as this can cause electric shock.
During maintenance do not allow any unauthorized person to stand near the machine.
Be sure you fully understand the contents of the operation. It is important to prepare necessary tools
and parts and to keep the operating area clean.
When checking an open gear case there is a risk of dropping things in. Before removing the covers to
inspect such cases, empty everything from your pockets. Be particularly careful to remove wrenches
and nuts.
Way to use dipstick
Push the dipstick fully into the guide, and then pull out.
Carrying out other difficult maintenance work carelessly can cause unexpected accidents. If you
consider the maintenance is too difficult, always request the HYUNDAI Forklift distributor to carry out
it.
