3. Select the direction of impact desired using the ro-
tary reversing valve located on the left side of the
wrench. To select clockwise direction, move the le-
ver toward the front (drive end) of the wrench. To
select counterclockwise direction, move the lever to
the rear (handle end) of the wrench.
NOTE:
To more accurately tighten bolts, lubricate threads,
check with a torque wrench and 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
If the wrench is to be used during cold weather, preheat
the hydraulic fluid at low engine speed. When using the
normally recommended fluids, fluid temperature should
be at or above 50 °F/10 °C (400 ssu/82 centistokes) be-
fore use.
Damage to the hydraulic system or wrench can result
from use with fluid that is too viscous or too thick.
