Operating Instructions
develops a flow of 4-12 gpm/ 15-45 lpm at
2000 psi/ 140 bar.
2. Make certain the hydraulic power source is
equipped with a relief valve set to open at
2100 psi/ 145 bar maximum.
Connect Hoses
1. Wipe all hoses with a clean lint-free cloth
before making connections.
2. Connect the hoses from the hydraulic power
source to the hose couplers on the tool. It is a
good practice to connect the return hose first
and disconnect it last to minimize or avoid
trapped pressure within the tool.
3. Observe flow indicators stamped on hose
couplers to be sure that oil will flow in the
proper direction. The female coupler is the
inlet coupler.
NOTE: The pressure in uncoupled hoses left in
the sun may result in making them difficult to
connect. When possible, connect the free ends of
the operating hoses together.
Wrench Operation
Use a larger capacity impact wrench model for jobs
requiring continuous application of greater than 500 ft
lb/ 675 Nm of torque on successive fasteners or
requiring impact times to constantly exceed 10
seconds.
1. Observe all safety precautions.
2. Move the hydraulic circuit control valve to the
ON position to operate the wrench.
WARNING
Always use sockets and accessories designed for impact type
applications. DO NOT USE STANDARD SOCKETS OR
ACCESSORIES. THESE CAN CRACK OR FRACTURE DURING
OPERATION.
3. Select the direction of impact desired using
the reversing spool located on the side of the
wrench. From the operator's view point, to
tighten fasteners, push the right hand end of the
valve IN. To loosen fasteners, push the left hand
end of the valve IN.
NOTE: To more accurately tighten bolts, lubricate
threads and check with a torque wrench.
Duplicate time of impacting for other bolts of the
same length and thread size.
4. Squeeze the trigger to activate the wrench.
5. Release the trigger to stop the wrench.
Cold Weather Operation
1.
Before using the tool in cold weather, preheat
the hydraulic fluid at low engine speed. When
using the normally recommended oils, oil
temperature should be at or above
(400 ssu/82 centistokes) before use.
2. Damage to the hydraulic system or tool can
result from use with oil that is too viscous or
thick.
Daily Maintenance Checks
To ensure safe operation, the following items must be
checked each day at the start of the work shift and at
the end of the work shift.
1. Check all fasteners for tightness.
2. Check the tool for oil leaks. If leaks are
observed, do not use the tool. Have the tool
serviced before use.
3. Check the tool for proper operation and
performance. If the tool appears to not be
operating properly , do not use the tool. Have
the tool serviced before use.
