8.2 Safety precautions

8.2 SAFETY PRECAUTIONS

The following safety precautions should be used in conjunction with all other safety precautions found in this MANUAL.

WARNING

Read, understand and follow all safety precautions and operating procedures found in this manual before operating the machine or any attachment.

A.USE FOR INTENDED PURPOSE

Use the attachment only for its intended purpose. If not used in accordance with the manufactures instructions, the excessive pressure exerted on the boom, arm and frame structure of the machine will cause premature failure of the components.

B.PASSENGERS

Never allow passengers on the attachment or machine.

C.PROTECTIVE EQUIPMENT

When operating attachments that produce flying debris, it is highly recommended to procure and install protective guards on the machine and close the all window to protect the operator from flying debris. Also the operator and all personnel in the vicinity of the machine should wear protective gear such as safety shoes, hard hat, gloves and face shield or goggles.

D.CYLINDERS

Do not operate boom, arm or bucket cylinders at stroke ends when using a breaker attachment. Doing this can cause undue stress on the cylinder rods and result in damage.

E.AVOID CONTINUOUS OPERATION

Operate the nibbler/breaker in 30 sec. intervals.

Operation for longer than 30 sec. at a time can cause high oil temperatures and damage the accumulators, cylinder seals and possibly pump damage.

F.HOSE SURGE

Should the hydraulic hoses begin to surge or vibrate abnormally during operation of a

Breaker or Nibbler, immediately stop operation and contact your Dealer for assistance. This problem often is a result of damaged accumulators and can also result in valve failure.

G.DO NOT USE DROPPING FORCE

Never use the dropping force of the attachment to break or drive objects. This will cause extensive damage to the attachment and machine structure.

H.DO NOT USE SLEW FORCE

Never use the slew force of the machine for pushing or sliding objects. This will cause premature failure of the attachment and other machine components.

I. DO NOT LIFT

Never use an optional attachment to lift or transport objects or material. Doing so can cause extensive damage to the attachment, the machine structures or cause injury or death due to slipping or dropping of load due to improper attachment.

J.WORKING RANGES

WARNING

Never operate an optional attachment over the sides of the machine. Only operate over the front or rear of the machine.

The balance on the machine becomes unstable at the position shown in the right figure involving a possibility of turning over the machine. Never carry out the breaker work with this position.

NOTE: •Refer to this SECTION for the work with the other attachment than the hydraulic breaker, too. •Use the reinforced arm for the work with the hydraulic breaker, etc. The use of standard arm for such work may cause damages on the arm.

K.TO PRY AND BREAK FORCIBLY

Do not use the breaker to pry and break rock and concrete.

This may damage the hydraulic breaker, and also boom, arm and cylinder.

L.ARM IN VERTICAL POSITION

The arm should not be operated in the vertical position to prevent the arm cylinder from vertical shocks.

This may damage the rod packing and piston and cause the oil leaking from those sections.
