NEVER raise the truck by the overhead guard. If the truck has to be
lifted frequently, it is necessary to install special lifting equipment, so
pleas contact your Komatsu Forklift dealer.
Fit wire ropes to the specified lifting points.
When lifting the lift truck, check that the wire ropes have ample
strength and are not damaged.
Block the tires contacting the ground to prevent the lift truck from
moving.
Insert blocks to prevent the lift truck from coming down.
Do not go under the lift truck during the lifting operation.
If the specified lifting point is the counterweight, check that the
counterweight mounting bolts are tightened to the specified torque
before carrying out the lifting operation. Check also that there is no
damage to the lifting portion on the counterweight.
Battery electrolyte contains sulfuric acid and can quickly burn the
skin and eat holes in clothing. If you spill electrolyte on yourself,
immediately flush the area with a large quantity of water.
Battery electrolyte can cause blindness if splashed into the eyes. If
electrolyte gets into your eyes, flush them immediately with large
quantities of water and consult a doctor at once.
If you accidentally drink electrolyte, drink a large quantity of water or
milk mixed with beaten egg white or vegetable oil. Call a doctor or
poison control center immediately.
When working with batteries, ALWAYS wear safety glasses or
goggles.
Batteries generate hydrogen gas. Hydrogen gas is highly
EXPLOSIVE, and is easily ignited with a small spark or flame. Do not
smoke or create any spark near a battery.
Before inspecting or handling batteries, turn the starting switch to the
OFF position to stop the engine, then disconnect the battery plug.
When removing the battery, remove the cable from the negative (-)
terminal first. When installing the battery, install the cable to the
positive (+) terminal first. This prevents possible sparks or arcing
between the positive terminal and the positive cable.
Avoid short-circuiting the battery terminals through accidental contact with tools or other metal objects
across the terminals.
Tighten the battery terminals securely. Loose terminals can generate sparks and lead to an explosion.
When removing or installing the battery, confirm which is the positive (+) terminal and which is the
negative (-) terminal. Be careful not to connect the cables to the opposite / incorrect terminals.
Tighten the battery caps securely.
When cleaning the battery, leave the battery caps tightened.
If the battery plug is damaged or the screws are loose, there is danger of a short circuit. Always replace
the battery plug with a new part.
