needle eye may penetrate muscles and cause injuries. If solution is jetted to skin, it shall be

treated within a couple of hours by surgeons who are familiar with this kind of injury.

Asbestos

When handling parts that contain asbestos fiber, it shall be avoided to inhale in asbestos

dust, which is harmful. The products of Chenggong that contain asbestos are brake pad, brake

plate and some gaskets, the asbestos inside which are normally sealed with colophony or by

other means. As long as no air containing asbestos is generated, normal handling is harmless.

When asbestos dust is generated, follow the precautions below:

Never clean with compressed air.

Do not brush or abrade materials containing asbestos.

For better cleaning result, clean with wet cloth or vacuum equipment with high efficiency

dust/air separation filter screen.

Ventilate machining workstation of frequent use.

Wear proper breathing mask when there is no way to control asbestos dust.

Observe applicable laws and regulations in the work area.

Store asbestos in compliance with relevant environment laws and regulations.

3.7 Precautions for Crush or Cutting

During the operation of the machine,

the space between the front and rear

frames is not allowed to be entered.

When the machine is hoisted and loaded

on other machines, or when servicing at the

middle of the machine, the lock rod shall be

installed between the front and rear frames

to keep the machine in a straight position.

When the machine is hoisted and loaded on

other machines, or when servicing at the middle of the machine, the lock rod shall be installed

between the front and rear frames to keep the machine in a straight position.

Lock rod

Lock rod is painted with red warning color. When it is in a lock status, it can prevent perilous

factors caused by relative movement of articulated front and rear frames in case of being under

unpredictable foreign force. When the lock rod is in a lock status, the machine cannot run.

The lock rod must be in a lock status in following circumstances:

During inspection, maintenance and repair of the machine;；

When preparing to leave after finishing the work and stopping the engine each time;

When the machine is being hoisted;

During shipment of the machine;

Fix

1. Keep the front and rear frames in a straight position.

2. Take off the rear split pin at the rear lug with a wrench,

then take off the pin shaft from the bottom.

3. Rotate lock rod onward until the hole in the lock rod is

concentric with the hole at front lug (see the picture).

4. Insert the newly pulled out locking pin shaft from the

bottom and fix it with split pin. The front and rear frames

are now in a lock status.

Release

1. Take off the split pin at the front lug, then take off the pin

shaft from the bottom.

2. Rotate lock rod backward until the hole in the lock rod is

concentric with the hole at rear lug (see the picture).

3. Insert the pin shaft which was taken off from the bottom

and fix with the split pin. The front and rear frames are

now in a free status.

When servicing haudralic parts inside the front frame

or front axle and the movable arm is needed to be lifted, the bucket shall be located on

a solid platform to prevent it from falling and cause severe injuries. It is prohibited to

have anyone stand underneath the bucket or movable arm when the machine is

working.

When working underneath the machine, the machine and its attachments shall be

properly supported. Do not rely on hydraulic device to keep the stability of the machine. If

the control mechanism moves or hydraulic pipeline leaks, any attachment may fall off.

Instructions on use of protective safety stand for lift cylinder

Protective safety stand for lift cylinder is a safety protective device. It is fixed at the rear

frame. Before servicing the wheel loader, it shall be removed from the fixing position and

installed at the indicated places of the lift cylinder (as shown in the diagram). The orders of the

removal and installation is as follows:

1. Remove the protective device;

2. Install it at the specified positions of the lift cylinder (two places at the left and right side of

the oil cylinder);

文本筐

Fix the safety stand for oil cylinder into the piston rod of oil cylinder when repairing.

3. Install and fasten tightly its fixing bolt.

文本筐

: When not repairing, fix the protective device for the oil cylinder at the rear frame.

Unless otherwise specified, no adjustment shall be made when the machine is working or

the engine is running.

At the linkage mechanism of the work device, in accordance with the movement of the

work device, the space at the linkage mechanism may increase or decrease.

Keep away from all rotating and moving parts.

Ensure that there is no any foreign matter between the fan blades. Fan blades will throw out

or cut the tools or other foreign matters which fall inside or are pushed inside.

Donot use twisted or worn wires or cables. Weare gloves when handling wires and cables.

When removing bouncy objects, such as snap ring or closing ring, wear protective goggles

to protect eyes. Take care to check whether anyone is nearby in case injury being inflicted

to other people.

When dissembling parts by hammering, fragments may fly over. Take care not to cause

injuries.

3.8 Precautions in Using FOPS & ROPS (falling object protection structure

or rollover protection structure)

The rollover protection structure (ROPS) and falling object protection structure (FOPS) of

the wheel loaders of Chengdu Contruction Machinery Co. Ltd are mounted ouside the cab

framework。The FOPS & ROPS are for protection of operator in case of heavy objects falling

down from above or rollover of the machine. The ROPS will not only bear the load when the

machine is rolling over, but also absorb impact energy.

If the device is damaged by falling or rollover, its strength will decrease and it will be

unable to perform its protective functions. For this instance, please contact with Chengdu

Contruction Machinery Co. Ltd or its approved dealers to consult for repair method.

Even if the POPS is installed, the operators must fasten safety belt for effective protection.

Even if no defect is discovered of the safety belt, it shall be replaced evrey three years.

It is prohibited to bore or weld inside or outside of ROPS, otherwise the strength of ROPS

may be lowered.
