IW16 User Manual ◄ 13
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) before
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
After each use, the movable portions of the tool that were exposed to water should be ushed with a water displacing
oil, such as WD-40™. Remove any remaining water and debris as follows:
1. Spray oil throughout all moving parts and any areas exposed to water.
2. Spray oil into the On/O valve trigger slot area.
3. Dip or spray the entire tool.
4. Cycle the tool hydraulically several times before storing away.
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 mechanism as described in the IW16 Service Manual.

EXTENSION HANDLE
