SAFETY GUIDELINES
Please read and ensure that you understand all of the operating instructions, safety
precautions and warnings in this Instruction Manual before operating or maintaining this
equipment. An accident can often be avoided by recognizing a potentially hazardous
situation before it occurs, and by observing the appropriate safety procedures. Never use
this equipment or modify it in any way that has not been specically recommended by the
manufacturer. Contact a qualied electrician for advice on any issues relating to electrical
safety in your working environment.
GENERAL EQUIPMENT SAFETY
• Inspect the grease gun and the power tool for damage and ensure all connections are secure before use. Do not
use the equipment if damage is detected.

ELECTRICAL SAFETY FOR POWER TOOLS
Ensure that you check the equipment thoroughly to ensure it is safe and t for purpose before each
use. It is important that you inspect all plugs, sockets, power cables and electrical ttings for wear
and damage and repair or replace any defective components. The risk of electric shock can be
minimised by the correct use of the appropriate electrical safety devices.
• We recommend that you t a Residual Current Circuit Breaker (RCCB) in the main distribution board and that a
Residual Current Device (RCD) is used when operating this equipment.
• The Electricity at Work Act 1989 includes legislation that places legal implications on employers to ensure
the safety of electrical devices in the workplace. The regulations dictate that all portable equipment must be
inspected regularly and tested to ensure that it is safe for use. 'Portable equipment' means any electrical item
that can be moved and this is often referred to as Portable Appliance Testing (PAT). PAT testing should be carried
out regularly on this equipment by trained, authorised personnel, as required by the legislation.
• The Health and Safety at Work Act 1974 states that it is the responsibility of the owner of electrical appliances to
ensure that both the equipment and working environments are maintained to ensure safe operation at all times.
• Check that all equipment cables are secure, correctly insulated, free from damage, and protected against short
circuit and overload before connecting to the power supply. Do not use worn or damaged cables, plugs, sockets
or other ttings.
• Ensure that the power supply matches voltage requirements specied on the equipment and that the plug is
wired correctly and tted with the correct fuse.
• If the electrical fuse blows, ensure it is replaced by an identical type of fuse with the same rating.
• Never pull or manoeuvre this equipment into position using the power cable.
• Ensure the power cable is kept away from heat, oil and sharp edges.
• We recommend that the equipment is connected directly to the power supply without the use of extension leads
as the resulting voltage drop can reduce motor performance.
• Always disconnect the equipment from the power source before servicing, inspecting, maintaining, cleaning,
replacing or checking any parts.

Plunger Assembly).
2. Pull the Follower Handle back until the Rod is fully extended (carefully
release the follower handle to eject / remove used cartridge, if present).
Pull back the Follower Handle until fully extended then pull it sideways
to latch the Rod groove into the keyhole slot in the container cap (Fig.3)
3. Remove the caps from both ends of the Container Housing and insert
the open end of the cartridge with the metal rimmed end toward the
bottom cap / plunger end.
4. Loosely assemble the head and the Container Housing and disengage
the follower rod from the Container Cap. Engage the Follower Rod with
the Follower by rotating the Follower Handle.
5. Unscrew the Container Housing 1-2 turns from the Gun Head
