WRENCH OPERATION
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.
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 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 IW16 Service Manual.
EXTENSION HANDLE
If the handle and anchor block are removed, all valve
handle/motor housing bolts must be cleaned, installed
with 242 Loctite® and re-torqued. Contact Stanley au-
thorized service for procedure.
