Precautions When Working on Machine
When carrying out maintenance operations on the machine,
keep the area around your feet clean and tidy to prevent
you from falling. Always do the following:
• Do not spill oil or grease.
• Do not leave tools laying about.
• Watch your step when walking.
Never jump down from the machine. When getting on or off
the machine, use the steps and handrails, and maintain a
three-point contact (both feet and one hand or both hands
and one foot) to support yourself securely.
If the job requires it, wear protective clothing.
To prevent injury from slipping or falling, when working on
the hood or covers, never use any part except the
inspection passage fitted with nonslip pads.
Lock Inspection Covers
When carrying out maintenance with the inspection cover
open, lock the cover securely in position with the lock bar.
If maintenance work is carried out with the inspection cover
open but not locked, there is danger that it may suddenly
close and cause injury if there is a gust of wind.
Crushing Prevention and Cutting
Prevention
You should always have at least two people working
together if the engine must be run during service. One
person needs to remain in the operator's seat, ready to
work the controls or stop the machine and shut off the
engine.
Unless you are instructed otherwise, never attempt
adjustments while the machine is moving or while the
engine is running.
Stay clear of all rotating parts and moving parts.
Keep objects away from moving fan blades. The fan blades
will throw objects and the fan blades can cut objects.
Do not use a wire rope cable that is kinked or flayed. Wear
gloves when you handle a wire rope cable.
When you strike a retainer pin, the retainer pin might fly out.
The loose retainer pin can injure personnel. Make sure that
the area is clear of people when you strike a retainer pin.
To avoid injury to your eyes, wear protective glasses when
you strike a retainer pin.
