•
Use clamps or other practical ways to secure and support the workpiece to a stable platform. Holding the work by hand is unstable and may
lead to loss of control. Only work on a workpiece that is properly secured.
•
Do not force or modify the tool. Use the correct tool for your application.
•
Check for misalignment or binding of moving parts, breakages of parts, damaged air hose (not included), and any other condition that may
affect the tool's operation. If damage is detected ensure that you have the tool repaired before use.
•
Ensure you read, understand and apply safety instructions before use.
•
Only use impact sockets which are specifically designed for use with an impact wrench (contact your nearest Jefferson dealer for advice on
the best sockets to use.
•
Place the socket fully over the working nut and depress the trigger to operate the wrench.
•
Do not use any additional force upon the wrench in order to remove a nut.
•
Do not allow the wrench to free-run for an extended period of time as this will reduce bearing life.
•
To operate, check connections are correct and safe, pull the trigger on the handle.
•
To operate with a forward rotation move the lever on the rear of the wrench to the "F" position.
•
To operate with a reverse motion move the lever to the "R" position.
•
This equipment is designed as a “plug-and-run” type device.
•
The tool will stop operation/rotation in a few seconds after relieving the trigger control.
5. Maintenance
Lubrication
Before connecting the air hose, apply 4 to 5 drops of air line oil, or equivalent, at the air inlet. Repeat this process after every 3 to 4 hours of use
and as necessary. Do not lubricate tools with flammable or volatile liquids such as petrol, diesel or jet fuel.
Fittings
Check fittings and accessories daily and ensure all parts are fastened securely and in good working condition .
Cleaning
Ensure handle is kept clean and free from oil, dust and dirt to ensure that the equipment can be gripped securely.
Ensure that the handle is cleaned before and during use using a clean, dry cloth.
Storage
Ensure that the tool is stored in clean, dry environment. If the tool is not in use for a period of time, any residual moisture inside of the wrench
could result in rusting. Before storing after use, the wrench should be oiled at the air inlet with air line oil and allowed to operate for a short period
before storing.
Repairs
Ensure that all repairs are carried out by Jefferson authorised engineers or at your nearest authorised Jefferson Repair Centre.
