5. HEALTH AND SAFETY INFORMATION
5.1 GENERAL SAFETY INSTRUCTIONS FOR POWER TOOL USE
When using any type of power tool there are steps that should be taken to make sure that you, as the
user, remain safe.
Common sense and a respect for the tool will help reduce the risk of injury.
Read the instruction manual fully. Do not attempt any operation until you have read and understood
this manual.
Most important you must know how to safely start and stop this machine, especially in an emergency.
Keep the work area tidy and clean. Attempting to clear clutter from around the machine during use
will reduce your concentration. Mess on the floor creates a trip hazard. Any liquid spilt on the floor
could result in you slipping.
Find a suitable location. If the machine is bench mounted, the location should provide good natural
light or artificial lighting as a replacement. Avoid damp and dust locations as it will have a negative
effect on the machine’s performance. If the machine is portable do not expose the tool to rain. In all
cases do not operate power tools near any flammable materials.
Keep bystanders away. Children, onlookers and passers by must be restricted from entering the work
area for their own protection. The barrier must extend a suitable distance from the tool user.
Unplug and house all power tools that are not in use. A power tool should never be left unattended
while connected to the power supply. They must be housed in a suitable location, away locked up and
from children. This includes battery chargers.
Do not overload or misuse the tool. All tools are designed for a purpose and are limited to what they
are capable of doing. Do not attempt to use a power tool (or adapt it in any way) for an application it is
not designed for. Select a tool appropriate for the size of the job. Overloading a tool will result in tool
failure and user injury. This covers the use of accessories.
Dress properly. Loose clothing, long hair and jewellery are all dangerous because they can become
entangled in moving machinery. This can also result in parts of body being pulled into the machine.
Clothing should be close fitted, with any long hair tired back and jewellery and neck ties removed.
Footwear must be fully enclosed and have a non-slip sole.
Wear personal protective equipment (PPE). Dust, noise, vibration and swarf can all be dangerous if
not suitably protected against. If the work involving the power tool creates dust or fumes wear a dust
mask. Vibration to the hand, caused by operating some tools for longer periods must be protected
against. Wear vibration reducing gloves and allow long breaks between uses. Protect against dust and
swarf by wearing approved safety goggles or a face shield. These are some of the more common
hazards and preventions, however, always find out what hazards are associated with the
machine/work process and wear the most suitable protective equipment available.
Do not breathe contaminated air. If the work creates dust or fumes connect the machine (if possible)
to an extraction system either locally or remotely. Working outdoors can also help if possible.
Move the machine as instructed. If the machine is hand held, do not carry it by the power supply
cable. If the product is heavy, employ a second or third person to help move it safely or use a
mechanical device. Always refer to the instructions for the correct method.
Do not overreach. Extending your body too far can result in a loss of balance and you falling. This
could be from a height or onto a machine and will result in injury.
Maintain your tools correctly. A well maintained tool will do the job safely. Replace any damaged or
missing parts immediately with original parts from the manufacturer. As applicable, keep blades sharp,
moving parts clean, oiled or greased, handles clean, and emergency devices working.

5. HEALTH AND SAFETY INFORMATION
Wait for the machine to stop. Unless the machine is fitted with a safety brake, some parts may
continue to move due to momentum. Wait for all parts to stop, then unplug it from the power supply
before making any adjustments, carrying out maintenance operations or just finishing using the tool.
Remove and check setting tools. Some machinery requires the use of additional tools or keys to set,
load or adjust the power tool. Before starting the power tool always check to make certain they have
been removed and are safely away from the machine.
Prevent unintentional starting. Before plugging any machine in to the power supply, make sure the
switch is in the OFF position. If the machine is portable, do not hold the machine near the switch and
take care when putting the machine down, that nothing can operate the switch.
Carefully select an extension lead. Some machines are not suitable for use with extension leads. If
the tool is designed for use outdoors, use an extension lead also suitable for that environment. When
using an extended lead, select one capable of handling the current (amps) drawn by the machine in
use. Fully extend the lead regardless of the distance between the power supply and the tool. Excess
current (amps) and a coiled extension lead will both cause the cable to heat up and can result in fire.
Concentrate and stay alert. Distractions are likely to cause an accident. Never operate a power tool if
you are under the influence of drugs (prescription or otherwise), including alcohol or if you are feeling
tired. Being disorientated will result in an accident.
Have this tool repaired by a qualified person. This tool is designed to conform to the relevant
international and local standards and as such should be maintained and repaired by someone
qualified, using only original parts supplied by the manufacturer. This will ensure the tool remains safe
to use.
5.2 SPECIFIC SAFETY INSTRUCTIONS FOR NIBBLERS
NIBBLER SAFETY WARNINGS
1. Hold the tool firmly.
2. Secure the workpiece firmly.
3. Keep hands away from moving parts.
4. Cut edges and the chips that are produced from the workpiece are sharp.
Wear gloves. We also recommended that you put on thickly bottomed shoes and trousers or
other garments that cover the top of your shoes to prevent injury.
5. Do not put the tool down on the chips of the workpiece. It can damage the tool.
6. Do not leave the tool running. Operate the tool only when hand-held.
7. Always be sure you have a firm footing.
Be sure no one is below when using the tool in high locations.
8. Do not touch the punch, die or the workpiece immediately after operation; they may be
extremely hot and could burn your skin.
9. Avoid cutting electrical wires. It can cause serious accident by electric shock.
SAVE THESE INSTRUCTIONS.
5.3 RESIDUAL RISK
Important note: Although the safety instructions and operating manuals for our tools contain extensive
instructions for safe working with power tools, every power tool involves a certain residual risk which
can not be completely excluded by safety mechanisms. Power tools must therefore always be
operated with caution!

8.5 REMOVING AND INSTALLING
HEADS
To change cutter heads, first undo the lock nut with
supplied spanner and continue to loosen until it is
free from the threads (Fig.6).
Grasp the cutter head and pull in a perpendicular
direction to the body of the tool.
The cutter head should slide out of the tool easily
(Fig.7).
FIG.7

- 13 -
FIG.9
To install a cutter head, the cutter needs to be
located in the plunger first, then slide the correct
cutter head over the cutter and locate in the tool, this
may be tricky at first as the cutter needs to line up
accurately to locate the cutter head, it may be easier
to allow the cutter to hang from the plunger (Fig.8.)
and slide the cutter head into place from underneath
with the rapid cutter you may need to slacken the
bolts holding the upper guide on to allow it to slide
easily into place (Fig.10.). You also need to line up
the groove in the cutter with the rear of the cutter
head (Figs.9-10). Don’t tighten the bolts up too much
or you may restrict the removal of the cutter head.
Once the cutter head is fully located rotate the head
until it locks into position (the freehand head locks in
two positions 180deg apart and the rapid nibbler
head locks into 4 positions 90deg apart) once
located tighten up the lock nut with the supplied
spanner.

9. BASIC NIBBLER OPERATION
9.1 CUTTING METHOD
Hold the machine 90°to the cutting sheet, move the
machine slowly.
When using the rapid nibbler you can cut straight
lines and slight curves.
When using the freehand nibbler head you can cut
curves down to a radius of 25mm.
If you wish to cut out from the middle of a sheet, you
need to drill a hole 16mm or larger to provide
clearance for the head to be inserted in the sheet.
