3. CONVERSION TABLE
Method of using the Conversion Table
The Conversion Table in this section is provided to enable simple conversion of figures. For details of
the method of using the Conversion Table, see the example given below.
Example
Method of using the Conversion Table to convert from millimeters to inches
Convert 55
mm into inches.
Locate the number 50
in the vertical column at the left side, take this as ⓐ, then draw a
horizontal line from ⓐ.
Locate the number 5
in the row across the top, take this as ⓑ, then draw a perpendicular line
down from ⓑ.
Take the point where the two lines cross as ⓒ. This point ⓒgives the value when converting
from millimeters to inches. Therefore, 55
mm = 2.165 inches.
Convert 550
mm into inches.
The number 550 does not appear in the table, so divide by 10(Move the decimal point one place
to the left) to convert it to 55
mm .
Carry out the same procedure as above to convert 55mm to 2.165 inches.
The original value(550
mm ) was divided by 10, so multiply 2.165 inches by 10(Move the decimal
point one place to the right) to return to the original value.
This gives 550
mm = 21.65 inches.

TEMPERATURE
Fahrenheit-Centigrade Conversion.
A simple way to convert a fahrenheit temperature reading into a centigrade temperature reading or vice verse
is to enter the accompanying table in the center or boldface column of figures.
These figures refer to the temperature in either Fahrenheit or Centigrade degrees.
If it is desired to convert from Fahrenheit to Centigrade degrees, consider the center column as a table of
Fahrenheit temperatures and read the corresponding Centigrade temperature in the column at the left.

Group 3 Periodic replacement 1-13

1-1
Careless performing of the easy work may cause injuries.
Take care to always perform work safely, at least observing the following.
Oil is a dangerous substance. Never handle
oil, grease or oily clothes in places where
there is any fire of flame.
As preparation in case of fire, always know the
location and directions for use of fire extinguishers
and other fire fighting equipment.
··
Wear well-fitting helmet, safety shoes and
working clothes. When drilling, grinding or
hammering, always wear protective goggles.
Always do up safety clothes properly so that
they do not catch on protruding parts of
machines. Do not wear oily clothes.
When checking, always release battery plug.
··
Flames should never be used instead of
lamps. Never use a naked flame to check
leaks or the level of oil or electrolyte.
··
Exhaust gas is dangerous. Provide adequate
ventilation when working a closed space.

GROUP 1 SAFETY HINTS

1-2
Be particularly careful when removing the
radiator cap and the hydraulic oil tank filler
cap, if this is done immediately after using the
machine, there is a danger that boiled oil may
spurt out.
The procedure for releasing the hydraulic
pressure is as follows : lower the fork to the ground,
and stop the engine(Motor), move the control
levers to each position two or three times.
··
When working on top of the machine, be
careful not to lose your balance and fall.
··
Hand a caution sign in the operator's compartment
(For example Do not start or Maintenance
in progress).
This will prevent anyone from starting or
moving the machine by mistake.
It is extremely dangerous to try to check the
fan belt tension while the engine is running.
··
When inspecting the engine is running parts, or
near such parts, always stop the engine first.
Before checking or servicing accumulator or
piping, depress brake pedal repeatedLy to
release pressure.
Park the machine on firm, flat ground.
Lower the fork to the ground and stop the
engine.
Return each lever to NEUTRAL and apply
the brake lock.

D35ASF08

1-3
Immediately remove any oil or grease on the
floor of the operator's compartment, or on the
handrail. It is very dangerous if someone
slips while on the machine.
··
OIL
When working with others, choose a group
leader and work according to his instructions.
Do not perform any maintenance beyond the
agreed work.
··
Unless you have special instructions to the
contrary, maintenance should always be
carried out with the engine stopped. If
maintenance is carried out with the engine
running, there must be two men present : one
sitting in the operator's seat and the other one
performing the maintenance. In such a case,
never touch any moving part.
··
Always remember that the hydraulic oil circuit
is under pressure. When feeding or draining
the oil or carrying out inspection and
maintenance, release the pressure first.
··
D35ASF09
D35ASF10
D35ASF11

1-4
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.
