3 SAFETY OPERATION

3.1 Be Familiar with Machine

z Study the operation manual for the machine. Learn

the structure of the machine, operation and

maintenance. Be familiar with the positions and

functions of the buttons, operation handles, meters

and warning devices.

z Know all the rules in operation; understand the

gestures of signaling staff.

z If there is any oil near the operating positions that

can cause slippage, clean it immediately.

z Check all the safety items, for example, the safety

protective devices should be at the safe status. Make

sure the tires are not worn and the tire pressure is

normal. Routinely check for oil leaks, water leaks,

air leaks, deformation, loose fittings and abnormal

sounds or accidents may occur. Check the safety

devices routinely.

3.2 When Leaving Operator’s Seat

z Always keep the parking brake switch in the lock

position.

z Level the working equipment completely to the

ground and put the gear control lever and working

equipment control handle in the neutral position,

then stop the engine and turn off the starting switch.

z Check the handrails and pedals, and if there is oil, lubricant or dirt clean them first to prevent

slippage. Repair the broken items and fasten the

loose nuts.

z Never jump on or off the machine. Never get on or

off a moving machine.

z When getting on or off the machine, face the machine and use the

handrails and pedals to ensure that you can support yourself. Keep at

least three-point contact (two hands/one foot or two feet/one hand)

with the handrails and pedals to ensure body stability.

z Never hold any control levers when getting on or off the machine.

z Never get into the operator cab from the ladder at the back of machine or get off from the wheel

at the side of operator cab.

z Never hold any tools or other items when climbing up and down the loader; lift the tools needed

to the operation flat roof by rope.

3.4 Fire Prevention

The following fluids are flammable and must be kept away from high heat and fire engine: lubricant
for loader engine, hydraulic oil for hydraulic system, hydraulic pressure shafting oil and gear oil for
transmission system, brake fluid and antifreeze fluid for heat elimina

tion

system.

Observe the following:

z Keep fire away from flammable fluids.
z Add refueling and lubricating oil in well-ventilated

areas. Stop the engine and no smoking while
refueling.

z Tighten all fuel and oil tank caps firmly.
z Put the above flammable liquids in containers with

relevant tags and put in a separate, proper place for

storage. Do not allow unauthorized people to use.

z Electric welding and flame cutting is not allowed for the tubes containing flammable fluid. Clean

the tubes with nonflammable fluid before electric welding and flame cutting.

z Clean thoroughly the flammable materials such as sawdust, leaves and paper which collect in the

engine and brake clip, and clean the flammable oil, lubricating oil and other substances on the
machine.

z While operating, pay attention when the outlet of the muffler is close to flammable materials such

as withered grass and old papers.

z When parking the loader, carefully select the environment; especially select the places where

there are no flammable materials near the parts with a high temperature such as the muffler.

z Check whether there is the leakage of fuel, lubricating oil, or hydraulic oil. If so, repair or replace

the broken items. Clean the repaired items before
use.

z If there is explosive air generated near the storage

battery, be sure there is no flame or fire nearby.
Repair, maintain and use the storage battery as
referenced in users manual.

z Do not use flame or fire (match or lighter) to check

in a dark place.

z The fire extinguisher should be ready for use at all

times and the user must be knowledgeable about its use and function. Check and maintain it as
referenced in users manual.

z Never operate machine near flame or fire.
z Do not short circuit.

3.5 Precautions When Operating at High Temperature

z Just after turning off the engine, the coolant, engine oil and hydraulic oil are at high temperature

and still under high pressure. The attempt to remove the cap, drain the oil or water, or replace

filters may lead to serious burns. Always wait for the

temperature to go down, and follow the specified

procedures when performing these operations.

z Stop the engine, wait for the water to become cool,

and then loosen the cap slowly to relieve the inner

pressure before removing the cap of radiator.
