For safe operations
For safe operations:
1) Work area
a. Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b. Consider work area environment. Do not expose power tools to rain. Do not use
power tools in damp or wet locations. Keep work area well lit. Do not use power tools
where there is risk to cause re or explosion.
c. Do not operate power tools in explosive atmospheres, such as in the presence of
ammable liquids, gasses or dust. Power tools create sparks which may ignite the
dust of fumes.
c. Keep children away. Do not let vistors touch the tool or extension cord. All visitors
should be kept away from area.
2) Electrical safety
a. Power tool plugs must match the outlet. Never modify the plug in any way. Do not
use any adapter plugs which earthed (grounded) power tools. Unmodied plugs and
matching outlets will reduce risk of electric shock.
b. Guard against electric shock. Avoid body contact with earthed or grounded surfaces
such as pipes, radiators, ranges and refrigerators. There is an increased risk of
electric shock if your body is earthed or grounded.
c. Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
d. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
power tool.
Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.
e. When operating a power tool outdoors, use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk of electric shock. Always
use tool in conjunction with a residual circuit breaker device.
3) Personal safety
a. Stay alert, watch what you are doing and use common sense when operating a
power tool.
Do not use a power tool while you are tired or under the inuence of drugs, alcohol or
medication.
A moment of inattention while operating power tools may result in serious personal
injury.
b. Use safety equipment. Always wear eye protection. Safety equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.

3
c. Avoid accidental starting. Ensure the switch is in the o󰀨 position before plugging in.
Carrying power tools with your nger on the switch or plugging in power tools that
have the switch on invites accidents.
d. Remove any adjusting key or wrench before turning the power tool on. A wrench or a
key left attached to a rotating part of the power tool may result in personal injury.
e. Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
f. Dress properly. Do not wear loose clothing or jewellery, they can be caught in
moving parts. Rubber gloves and nonskid footwear are recommended when working
outdoors. Wear protecting hair covering to contain long hair.
g. If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of these devices can reduce
dust related hazards.
h. Use clamps or a vice to hold work. It’s safer than using your hand and it frees both
hands to operate tool.
4) Power tool use and care
a. Do not force the tool. It will do the job better and safer at the rate for which it was
intended.
b. Do not use the power tool if the switch does not turn it on and o󰀨. Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
c. Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures reduce the
risk of starting the power tool accidentally.
d. Store idle tools. When not in use, tools should be stored in a dry, high or locked up
place, out of reach of children.
e. Maintain power tools. Check for misalignment or binding of moving parts, breakage
of parts and any other condition that may a󰀨ect the power tools operation.
If damaged, have the power tool repaired before use. Many accidents are caused by
poorly maintained power tools.
f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
g. Use the right tool. Do not force small tools or attachments to do the job of a heavy
duty tool. Do not use tools for purpose not intended; for example, do not use circular
saws to cut tree limbs or logs.
h. Damaged switches must be replaced at a customer service repair centre. Do not use
power tools that cannot be switched on and o󰀨.
i. Do not leave power tools unattended while they are switched on. Always switch o󰀨
the tool and wait until it has come to a full standstill before leaving.

j. If the mains cable has been damaged, it must be replaced with a special mains
cable. These can be obtained from the manufacturer or the manufacturer's customer
service department. The mains cable may only be replaced by the manufacturer, the
manufacturer's customer service department or equally qualied persons.
5) Service
a. Please use a qualied expert who uses original replacement parts to repair your
power tool. This will ensure proper functioning of the power tool.
b. Caution! The use of any accessories or additional tools other than those
recommended in this manual may lead to an increased risk of injury. Only use
original replacement parts.
Safety Instructions for Spray Guns
• You may only spray coating materials such as paints, varnishes, glazes, etc. with a
ashpoint of 55°C and higher without additional warning. (German classifcation of
coating material is hazard classes A II and A III, see material tin.)
• The device may not be used in workplaces covered by the explosion-protection
regulations.
• There must be no sources of ignition such as, for example, open fres, smoke of lit
cigarettes, cigars and tobacco pipes, sparks, glowing wires, hot surfaces, etc. in the
vicinity during spraying.
• Do not spray any substances whose hazard potential is not known.
• Before working on the spray gun remove the power plug from the socket.
• Do not use the spray guns to spray ammable substances.
• The spray guns are not to be cleaned with ammable solvents which have a
ashpoint under 55°C.
• Caution against dangers that can arise from the sprayed substance and observe the
text and information on the containers or the specications given by the substance
manufacturer.
Recommendation: Wear a breathing mask and safety glasses when spraying.
CAUTION - DANGER OF INJURY!
Never point the spray gun at yourself, at other people or at animals.
• When working with the tool indoors as well as outdoors ensure that no solvent vapors
are sucked in by the spray gun.

• When working outdoors, be aware of the wind direction. Wind can carry the coating
substance across greater distances - thus causing damage. When working indoors,
provide for adequate ventilation.
• Do not let children handle the device.
• Never open the device yourself in order to carry out repairs in the electrical system!
• Do not lay the spray gun.
Residual risks
Even when the power tool is used as prescribed it is not possible to eliminate all
residual risk factors. The following hazards may arise in connection with the power
tool’s construction and design:
1. Damage to lungs if an e󰀨ective dust mask is not worn.
2. Damage to hearing if e󰀨ective hearing protection is not worn.
3. Damages to health resulting from vibration emission if the power tool is being used
over longer period of time or not adequately managed and properly maintained.
WARNING! This power tool produces an electromagnetic eld during operation. This eld
may under some circumstances interfere with active or passive medical implants. To
reduce the risk of serious or fatal injury, we recommend persons with medical implants
to consult their physician and the medical implant manufacturer before operating this
machine.

Wear hearing protection while operating the power tool.
The declared vibration total value has been measured in accordance with a standard
test method and may be used for comparing one tool with another.
The declared vibration total value may also be used in a preliminary assessment of
exposure.
Warning
The vibration emission during actual use of the power tool can di󰀨er from the declared
total value depending on the ways in which the tool is used.
There is the need to identify safety measures to protect the operator that are based on
an estimation of exposure in the actual conditions of use (taking account of all parts
of the operating cycle such as the times when the tool is switched o󰀨 and when it is
running idle in addition to the trigger time).
