OPERATION
COLD WEATHER OPERATION
If the wrench is to be used during cold weather, preheat
the hydraulic uid at low engine speed. When using the
normally recommended uids, uid 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 uid that is too viscous or too thick.
POST OPERATION
UNDERWATER MODELS ONLY
The wrench impact mechanism must be cleaned and
greased with waterproof grease after every day of use.
The main housing valve and motor are sealed and do
not require maintenance unless they are malfunctioning.
Remove, clean, grease and assemble the impact mech-
anism as described in the IW24 Service Manual.
3.
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.
Select the direction of impact desired using the re-
versing valve located on the side of the wrench. To
select clockwise direction, place the valve in the up-
ward position. To select counter-clockwise direction,
place the valve in the downward position.
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.
