High pressure fluid in the hoses can be very dangerous. If the
hose develops a leak, split or rupture due to any kind of wear,
damage or misuse, the high pressure spray emitted from it
can cause a fluid injection injury or other serious bodily injury
or property damage.
All fluid hoses must have spring guards on both ends!
The spring guards help protect the hose from kinks or bends
at or close to the coupling which can result in hose rupture.
Tighten all fluid connections securely before each use. High
pressure fluid can dislodge a loose coupling or allow high
pressure spray to be emitted from the coupling.
Never use a damaged hose. Before each use, check the en-
tire hose for cuts, leaks, abrasion, bulging cover, or damage
or movement of the hose couplings. If any of these conditions
exist, replace the hose immediately. Do not try to recouple
high pressure hose or mend it with tape or any other device.
A repaired hose cannot safely contain the high pressure fluid.
Handle and route hoses carefully. Do not pull on hoses to
move equipment. Do not use fluids which are not compatible
with the inner tube and cover of the hose. Do not expose
Graco hoses to temperatures above 82 C (180 F) or below
–40 C (–40 F).
United States Government safety standards have been adopted under the Occupational Safety and Health Act. These standards
– particularly the General Standards, Part 1910, and the Construction Standards, Part 1926 – should be consulted.

Hose Grounding Continuity
Proper hose grounding continuity is essential to maintaining a
grounded spray/dispensing system. Check the electrical re-
sistance of your air and fluid hoses at least once a week. If
your hose does not have a tag on it which specifies the maxi-
mum electrical resistance, contact the hose supplier or manu-
facturer for the maximum resistance limits. Use a resistance
meter in the appropriate range for your hose to check the
resistance. If the resistance exceeds the recommended lim-
its, replace it immediately. An ungrounded or poorly grounded
hose can make your system hazardous. Also, read FIRE OR
EXPLOSION HAZARD, on page 3.
MOVING PARTS HAZARD
The piston in the air motor moves when air is supplied to the
motor. Moving parts can pinch or amputate your fingers or
other body parts. Keep clear of moving parts when starting or
operating the pump. Before checking or servicing the pump
or any system component, follow the Pressure Relief Proce-
dure on page 2, to prevent the pump from starting acciden-
tally. Never operate the pump or air motor with the air motor
shield or any other parts removed.
Model 237–001, Reduced Icing Air Motor, has been added to
the manual.
The manual has been generally updated.
