Vibration hazards
Exposure to vibration can cause disabling damage to the nerves and blood supply of the hands and arms.
Keep the hands away from the nutrunner sockets.
Wear warm clothing when working in cold conditions and keep your hands warm and dry.
If you experience numbness, tingling, pain or whitening of the skin in your fingers or hands, stop using the
assembly pneumatic tool for threaded fasteners, tell your employer and consult a physician.
Operate and maintain the assembly pneumatic tool for threaded fasteners as recommended in the instruction
handbook, to prevent an unnecessary increase in vibration levels.
Do not use worn or ill-fitting sockets or extensions, as this is likely to cause a substantial increase in vibration.
Select, maintain and replace the consumable/inserted tool as recommended in the instruction handbook, to
prevent an unnecessary increase in vibration levels.
Sleeve fittings should be used where practicable.
Support the weight of the tool in a stand, tensioner or balancer, if possible.
Hold the tool with a light but safe grip, taking account of the required hand reaction forces, because the risk from
vibration is generally greater when the grip force is higher.
Additional safety instructions for pneumatic power tools
Air under pressure can cause severe injury:
Always shut off air supply, drain hose of air pressure and disconnect tool from air supply when not in use, before
changing accessories or when making repairs;
Never direct air at yourself or anyone else.
Whipping hoses can cause severe injury. Always check for damaged or loose hoses and fittings.
Cold air shall be directed away from the hands.
Do not use quick-disconnect couplings at tool inlet for impact and air-hydraulic impulse wrenches. Use hardened
steel (or material with comparable shock resistance) threaded hose fittings.
Whenever universal twist couplings (claw couplings) are used, lock pins shall be installed and whipcheck safety
cables shall be used to safeguard against possible hose-to-tool and hose-and-hose connection failure.
Do not exceed the maximum air pressure stated on the tool.
For torque-control and continuous-rotation tools, the air pressure has a safety critical effect on performance.
Therefore, requirements for length and diameter of the hose shall be specified.
Never carry an air tool by the hose.
Air supply
1. Ensure wrench air valve (or trigger) is in the “off”position before connecting to the air supply.
2. You will require an air pressure of 90psi, and an air flow according to specification.
3. WARNING! Ensure the air supply is clean and does not exceed 90psi while operating the wrench. Too high
an air pressure and unclean air will shorten the product life due to excessive wear, and may be dangerous
causing damage or personal injury.
4. Drain the air tank daily. Water in the air line will damage the wrench.
5. Clean air inlet filter weekly.
6. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The hose
diameter should be 3/8”I.D.
7. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections
are secure.
Lubrication
An automatic in-line filter-regulator-lubricator is recommended (Fig4) as it increases tool life and keeps the tool
in sustained operation. The in-line lubricator should be regularly checked and filled with air tool oil.
Proper adjustment of the in-line lubricator is performed by placing a sheet of paper next to the exhaust ports and
