3. PREPARING STAPLE GUN FOR USE

3.1 Air Supply

Recommended hook-up procedure is shown in fig 1.

3.1.1 Ensure tool air valve (or trigger) is in "off" position before connecting to the air supply.

3.1.2 You will require an air pressure of 90psi, and an air flow according to specification.

3.1.3  WARNING! Ensure the air supply is clean and does not exceed 90 psi while operating the tool. 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.

3.1.4 Drain the air tank daily. Water in the air line will damage the tool.

3.1.5 Clean air inlet filter weekly.

3.1.6 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.

3.1.7 Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all
connections are secure.

3.2 Couplings.

Vibration may cause failure if a quick change coupling is connected directly to the tool.
To overcome this, connect a leader hose to the tool. A quick change coupling may then be used to
connect the leader hose to the air line recoil hose. See fig 1 & 2.

4. OPERATING INSTRUCTIONS

Ensure you read, understand and apply safety instructions before use.

4.1.1 LOADING THE STAPLER

4.1.2 Load the magazine before connecting the airline. To open the magazine, release the magazine latch
(fig 3), be wary of spring release on the magazine. Load the staples into the loading slot with the tips
facing downwards, so the staples straddle the central ridge (fig 4).

4.1.3 Slide the magazine cover shut until it clicks into place behind the latch.

4.2.1 USING THE STAPLER

4.2.2 Before connecting to an air supply, ensure that the trigger catch release slide is not depressed. Connect
the air line to the staple gun as described in Section 3.

4.2.3 The operating trigger is normally locked and cannot be used until the safety switch is depressed. This
happens automatically as you position the staple gun.

4.2.4 Place the tip of the staple gun onto the material to be stapled and press downwards to bring the staple
outlet into contact with the surface. As the safety switch retracts the trigger will become free (fig 5).

4.2.5 Depress the trigger to fire one staple. To fire another staple, release the trigger, reposition the staple gun
at the next required stapling point and depress the trigger again. Repeat as necessary.

4.2.6 If you need to put the staple gun down during the course of working ensure that the safety switch is
not depressed against any object.

4.2.7 When the work is complete or when you have paused for any length of time, disconnect the staple gun
from the air line.

4.3.1 UNBLOCKING THE STAPLER

 WARNING! Should a blockage occur, disconnect staple gun from the air supply immediately.

4.3.2 Open the magazine (as described in 4.1.1)

4.3.3 Access the blockage by unclipping the driver guide front-plate (fig 6) using the release catch provided.

4.3.4 Remove the staple and any foreign matter found within the driver guide.

4.3.5 Replace the driver guide front-plate and set the catch.

4.3.6 Ensure that all parts of the staple gun are secure and correctly positioned, then reconnect the air supply.
