5.1 Important Items at Periodic Inspection and Maintenance or after
Maintenance
The manual shows proper interval for periodic inspection and maintenance under normally
operating conditions. Inspection and maintenance should be performed more often under
extremely harsh conditions.
Hang a “Now Checking and under Maintenance” tag
Remove the starter key from the starter switch before starting
inspection, and hang up a “Now Checking and under
Maintenance” tag where it can be easily seen. The checker must
keep the key during checking and maintenance.
Remove the negative (–) side cable from the battery.
If the above procedure is neglected, and another person starts
operating the machine during check or maintenance, it could
cause serious injury.
Use tools appropriate for the inspection and maintenance. Any
makeshift or improper tools could cause unexpectedly injury by
their slippage.
SY001
For protecting oil separator from fire accident
Be sure to perform oil change basically according to the
specified interval. But if such oil is found much more
contaminated before the interval, change the oil even before the
specified period comes. In doing so, replace the oil completely
and use our recommended oil.
Be sure to perform following periodic inspection and
maintenance:
1. Check and change compressor oil
2. Change oil separator
Never mix the oil of different brands, or the mixed oil may
deteriorate the oil quality.
