the hole has been complete to avoid damaging
the punch set. Never force points of punch into
contact with the die.

Maintenance Instructions

WARNING
Any repairs or service which requires dismantling
the pump or ram must be performed in a dirt-free
environment. All maintenance should be performed
by a qualified technician.

Lubrication

Apply lubrication periodically to all pivot and rubbing
points. Use a good grade of No. 10 motor oil. Do not
use dry lubricants.

Periodic Cleaning

A preventative maintenance program should be estab-
lished to keep the hydraulic components as free from
dirt as possible. Make certain that the hydraulic oil outlet
and all unused couplers are sealed with thread protectors
whenever the hydraulic system is dismantled. Be sure all
hose connections are free of contamination. Use only
an approved, clean hydraulic oil and change as recom-
mended, every 300 hours.
