# Operating the Low Profile Wrench

Prerequisites

- Wear personal protective equipment: Correct and appropriate safety equipment must be worn.

- Always perform a task-based risk assessment before using the tool.

- Frequently inspect the tool, power pack, hoses, connectors, electric cables, and accessories for visible damage. Always follow instructions for tool and pump maintenance.

- Select the appropriate size low clearance ratchet link and insert it into the tool. Tool operation, bolt tightening and loosening, is determined by the position of the tool relative to the nut/bolt.

- Connect the hoses: Make sure that all hose connections are secure and correctly made. Make sure that the hoses are free from defects.

Start up

1. Cycle the tool: Place the tool on a flat surface, turn the pump on. Press and hold the Advance [1] button on the pump remote control pendant until the tool clicks. Release the button, wait for the tool to click. Repeat.

2. Set the pressure: Press and hold the Advance [1] button and slowly turn the pressure regulator clockwise to reach the correct pressure.

3. Place the tool on the nut to be tightened or loosened.

   The driving stroke of the power head will always turn the hex ratchet (and therefore the nut) towards the shroud at the front of the tool, that is, turning away from the reaction point. The low clearance ratchet links are supplied complete with a long reaction block. This reaction block is designed to react against an adjacent nut.

The ratchet link has been designed so that the reaction block reacts against an adjacent nut or other suitable secure reaction point. If such a reaction point is not available, standard reaction accessories are available, or if necessary, special reaction arms can be supplied.

WARNING

Crushing Hazard

Keep hands away from the reaction areas during operation! The tool could entrap fingers or other body parts if not kept away. Moving parts can crush and cut.

Make sure that the nut corresponds with the tool size.

Always make sure to use a solid reaction point during operation.

Solid reaction point
Gap risk
NOTICE

Should a gap appear during use, stop operation.

Should a gap open up, the powerhead has not been secured to the ratchet link properly. This could cause damage to the tool.

- Insert the retaining pin.

Never kink or bend hoses excessively:

Never strike wrench to assist breakout:
