Safety Rules

Section 1 • Safety Rules

Danger

Failure to obey the instructions and safety rules in

this manual and the appropriate Operator's Manual

on your machine will result in death or serious

injury.

Many of the hazards identified in the operator's

manual are also safety hazards when maintenance

and repair procedures are performed.

Do not modify or alter a MEWP without prior written

permission from the manufacture.

You are trained and qualified to perform

maintenance on this machine.

You read, understand and obey:

- manufacturer’s instructions and safety rules

- employer’s safety rules and worksite

regulations

- applicable governmental regulations

You have the appropriate tools, lifting equipment

and a suitable workshop.

Personal Safety

Any person working on or around a machine must

be aware of all known safety hazards. Personal

safety and the continued safe operation of the

machine should be your top priority.

Read each procedure thoroughly. This

manual and the decals on the machine,

use signal words to identify the following:

Safety alert symbol—used to alert

personnel to potential personal

injury hazards. Obey all safety

messages that follow this symbol

to avoid possible injury or death.

Indicates an imminently hazardous

situation which, if not avoided, will

result in death or serious injury.

situation which, if not avoided,

could result in death or serious

injury.

Indicates a potentially hazardous

situation which, if not avoided,

may cause minor or moderate

injury.

Indicates a potentially hazardous

situation which, if not avoided,

may result in property damage.

SAFETY RULES

vii

Section 1 • Safety Rules

Workplace Safety

Be sure to keep sparks, flames and

lighted tobacco away from flammable and

combustible materials like battery gases

and engine fuels. Always have an approved fire

extinguisher within easy reach.

Be sure that all tools and working areas

are properly maintained and ready for use.

Keep work surfaces clean and free of

debris that could get into machine components and

cause damage.

Be sure any forklift, overhead crane or

other lifting or supporting device is fully

capable of supporting and stabilizing the

weight to be lifted. Use only chains or straps that

are in good condition and of ample capacity.

Be sure that fasteners intended for one

time use (i.e., cotter pins and self-locking

nuts) are not reused. These components

may fail if they are used a second time.

Be sure to properly dispose of old oil or

other fluids. Use an approved container.

Please be environmentally safe.

Be sure that your workshop or work area is

properly ventilated and well lit.
