CAUTION: Keep dirt and other foreign
matter out of hydraulic systems of the
tools, hoses, couplers and POWERIG
Hydraulic Unit. Do not let hose fittings and
couplers contact a dirty floor or unclean
working surface. Foreign matter in
hydraulic fluid may cause hydraulic unit
valves and tool valves to malfunction.
WARNINGS:
Operators of Huck Installation equipment
must always wear approved
eye protection.
Only Huck POWERIG ® Hydraulic Units
are recommended as the power source
for Huck tools. Units that deliver high
pressure for both PULL and RETURN,
and are not equipped with relief valves,
are specifically not recommended.
Severe personal injury or damage to
equipment may occur when using other
units.
Proper PULL and RETURN pressures are
important for proper function of
Installation Tools. Severe personal injury
or damage to equipment may occur with-
out correct pressures.
Gauge Set-up, P/N T-124833CE, is avail-
able for checking these pressures using
instructions furnished with T-124833CE
and in applicable POWERIG Hydraulic
Unit instruction manuals.
See Checking and Adjusting Output
Pressures.
