1.2 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.
WARNING! Disconnect from air supply before changing accessories or servicing.
Maintain the wrench in good condition and replace any damaged or worn parts. Use genuine parts only. Unauthorized parts may be dangerous and will invalidate the warranty.
WARNING! Check correct air pressure is maintained and not exceeded. We recommend 90psi.
Keep air hose away from heat, oil and sharp edges. Check air hose for wear before each use and ensure that all connections are secure.
WARNING! Due to the possible presence of asbestos dust from brake linings, when working around vehicle brake systems we recommend you wear suitable respiratory protection.
Keep children and non essential persons away from the working area.
DO NOT use the wrench for a task it is not designed to perform.
DO NOT operate wrench if you are tired or under the influence of alcohol, drugs or intoxicating medication.

SPECIFICATION

PREPARATION

4.1. For recommended hook-up, procedure is shown in figs 1 & 2.
4.2. AIR SUPPLY
4.2.1. Ensure wrench air valve (or trigger) is in the “off” position before connecting to the air supply.
4.2.2. You will require an air pressure of 90psi and an air flow according to specification.
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 and/or personal injury.
4.2.3. Drain the compressor air tank daily. Water in the air line will damage the wrench.
4.2.4. Clean compressor air inlet filter weekly.
4.2.5. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose diameter should be 1/4″ I.D. and fittings must have the same inside dimensions.
4.2.6. Keep hose away from heat, oil and sharp edges. Check hose for wear and make certain that all connections are secure.
4.3. COUPLINGS
4.3.1. Vibration may cause failure if a quick change coupling is connected directly to the wrench. To overcome this, connect a leader hose to the wrench. A quick change coupling may then be used to connect the leader hose to the air line recoil hose. See figs 1 & 2.

ASSEMBLY

5.1. Fit handle to the body in the desired orientation, fig.3.

OPERATION

WARNING! Ensure you read, understand and apply safety instructions before use.
6.1.1. Only use impact sockets which are specifically designed for use with an impact wrench.
6.1.2. Connect the wrench to the air hose as in Section 4.
6.1.3. Place the socket over the subject nut and depress the trigger to operate the wrench.
6.1.4. To change drive direction turn the control on the rear of the body to the desired direction, fig.3.
6.1.5. The torque may be adjusted in the forward gear by adjusting the torque control on the rear of the body, between 1 low power and 3 full power, fig.3.
6.1.6. The wrench incorporates two exhausts, one at the bottom of the handle and one at the front above the trigger. The handle exhaust is adjustable allowing you to adjust the flow through either the handle or front exhaust. When the handle exhaust is fully open the speed of the wrench is increased, when the handle exhaust is closed the wrench speed will decrease and the air will be vented through the front exhaust.
DO NOT use any additional force upon the wrench in order to remove a nut.
DO NOT allow wrench to free run for an extended period of time as this will shorten its life.

MAINTENANCE

❑ WARNING! Disconnect wrench from air supply before changing accessories, servicing or performing maintenance.
Replace or repair damaged parts. Use genuine parts only. Unauthorized parts may be dangerous and will invalidate the warranty.
7.1. If the air system does not have an oiler lubricate the air wrench daily with a few drops of Sealey air tool oil dripped into the air inlet.
7.2. Clean the wrench after use. DO NOT use worn or damaged sockets.
7.3. Loss of power or erratic action may be due to the following:
a) Excessive drain on the air line. Moisture or restriction in the air pipe. Incorrect size or type of hose connectors. To remedy, check the air supply and follow instructions in Section 4.
b) Grit or gum deposits in the wrench may also reduce performance. Remove the strainer, clean it and flush the wrench out with gum solvent oil or an equal mixture of SAE No 10 oil and paraffin. Allow to dry before use.
