Warning! the warnings, cautions and instructions in this manual cannot cover all possible conditions and situations that
may occur. it must be understood by the operator that common sense and caution are factors which cannot be built into
this product, but must be applied by the operator.
Warning! – risk of Hand arm Vibration injury.
this tool may cause Hand Arm Vibration syndrome if its use is not managed adequately.
this tool is subject to the vibration testing section of the machinery directive 2006/42/ec.
this tool is to be operated in accordance with these instructions.
measured vibration emission value (a): ............. 2.2m/s²
uncertainty value (k): ............................1.1m/s²
Please note that the application of the tool to a sole specialist task may produce a different average vibration emission. We recommend that a
specific evaluation of the vibration emission is conducted prior to commencing with a specialist task.
A health and safety assessment by the user (or employer) will need to be carried out to determine the suitable duration of use for each tool.
nB: stated Vibration emission values are type-test values and are intended to be typical.
Whilst in use, the actual value will vary considerably from and depend on many factors.
such factors include; the operator, the task and the inserted tool or consumable.
nB: ensure that the length of leader hoses is sufficient to allow unrestricted use, as this also helps to reduce vibration.
the state of maintenance of the tool itself is also an important factor, a poorly maintained tool will also increase the risk of Hand Arm Vibration
syndrome.
Health surveillance.
We recommend a programme of health surveillance to detect early symptoms of vibration injury so that management procedures can be
modified accordingly.

Personal protective equipment.
We are not aware of any personal protective equipment (PPe) that provides protection against vibration injury that may result from the
uncontrolled use of this tool. We recommend a sufficient supply of clothing (including gloves) to enable the operator to remain warm and dry and
maintain good blood circulation in fingers etc. Please note that the most effective protection is prevention, please refer to the correct use and
maintenance section in these instructions. Guidance relating to the management of hand arm vibration can be found on the Hsc website

4. preperatiOn
Warning! ensure the air supply is clean, dry and between 60 - 116psi while operating the nail gun. too high an air pressure and/
or unclean air will shorten the product life due to excessive wear, and may be dangerous causing damage and/or personal injury.
4.1. air Supply
4.1.1. ensure the nail gun trigger release slide is not depressed when connecting to the air supply. A gap of approximately 6mm between gun
housingandcatchwillbeevident(g.1).
4.1.2. You will require an air pressure of between 60 - 116psi.
4.1.3. drain your compressor air tank of water daily. Water in the air line will damage the nail gun.
4.1.4. clean the compressor air inlet filter weekly. recommended hook-up procedure is shown in fig.2.
4.1.5. 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.
4.1.6. Keep the hose away from heat, oil and sharp edges. check hose for wear, and make certain that all connections are secure.

5. OperatiOn
Warning! ensure you read, understand and apply safety instructions before use.
5.1. load the magazine before connecting the air line. to open the magazine, hold the nail gun body with the left hand, then with your
other hand, press the magazine latch lever and slide the magazine fully open. Place a “strip” of nails into the open magazine chamber,
ensuring that all the nails have their points resting on the bottom of the chamber.
5.2. slide the magazine cover shut until it clicks into place behind the catch.
5.3. Before connecting to an air supply, ensure that the trigger safety slide is notdepressed.Seethe6mmsafetydimensioning.1.
5.4. connect the air line to the nail gun as described in section 4.
5.5. the operating trigger is normally inoperable and cannot be used until the trigger safety slide is depressed. this happens automatically
as you position and offer the nail gun on to the timber work piece.
5.6. the trigger release slide can be seen protruding downwards just in front of the nail outlet (see fig.3). Place the tip of the slide onto the
timber work piece to be nailed and press downwards to bring the nail outlet into contact with the surface. As the slide retracts the trigger
will become operational. never depress the safety slide projection with your finger.
5.7. depress the trigger and release to fire one nail. to fire another nail in quick succession keep the trigger depressed, reposition the nail
gun at the next required nailing point and offer the nail gun on to the timber work piece. repeat as necessary.
5.8. if you need to put the nail gun down during the course of working, ensure that the trigger safety slide is not depressed against any
object closing the 6mm safety gap in fig.1. this would enable the trigger and possible accidental firing.
5.9. When the work is complete or when you have paused for any length of time, disconnect the nail gun from the air line.
Warning! should a blockage occur, disconnect the nail gun from the air supply immediately. see trouble shooting 6.2.

6. trOubleSHOOting
6.1. loss of power or erratic action:
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. flush the nail gun out with gum solvent oil or an equal mixture of
sAe no 10 oil and paraffin. Allow to dry before use.
c) Body air leaks, contact your service Agent.
6.2. nailing failure:
a) magazine empty. check for red indicators in fig.3, if red, reload with nails as described in 5.1 and 5.2.
b) Blockage in the magazine. disconnect from the air supply and open the magazine as described in 5.1. remove any obstructions,
check the nail strip, reload if necessary. close the magazine as described in 5.2.
c) Blockage in the ejector nose. disconnect from the air supply and completely remove 3 cap screws, the top nose plate and
intermediate plate in fig.4. ensure the compression spring is retained. clear the jam and replace all items.
d) nails not fully penetrating work piece. timber hardness or knots, may be a factor. Adjust the air pressure between 60-100psi.
