Precautions for Removal, Installation, and
Storage of Attachments
Before starting removal and installation of attachments, decide
the team leader.
Do not allow anyone except the authorized workers close to the
machine or attachment.
Place attachments that have been removed from the machine in
a safe place so that they do not fall. Put up a fence around the
attachments and take other measures to prevent unauthorized
persons from entering.
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.
