4 GENERAL POWER TOOL SAFETY WARNINGS
Read all safety warnings and all instructions. Failure to follow all warnings and instructions
may result in electric shock, fire and/or serious injury. Save all warnings and instructions for
future reference. The term "power tool" in the warnings refers to your mains operated (corded)
power tool or battery operated (cordless) power tool.

4.1 Work area
Keep work area clean and well lit. Cluttered and dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or
fumes.
Keep children and bystanders away while operating a power tool. Distractions can cause
you to lose control.
4.2 Electrical safety
Always check that the power supply corresponds to the voltage on the
rating plate.
Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching
outlets will reduce risk of 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.
Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
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.
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.
If operating a power tool in a damp location is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces the risk of electric shock.
4.3 Personal safety
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 influence of drugs, alcohol or
medication. A moment of inattention while operating power tools may result in serious
personal injury.
Use safety equipment. Always wear eye protection. Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection used whenever conditions require
will reduce personal injuries.
Avoid accidental starting. Ensure the switch is in the off position before plugging in.
Carrying power tools with your finger on the switch or plugging in power tools that have
the switch on invites accidents.
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.
Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in
moving parts.
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.

4.4 Power tool use and care
Do not force the power tool. Use the correct power tool for your application. The correct
power tool will do the job better and safer at the rate for which it was designed.
Do not use the power tool if the switch does not turn it on and off. Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
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.
Store idle power tools out of the reach of children and do not allow persons unfamiliar with
the power tool or these instructions to operate the power tool. Power tools are dangerous
in the hands of untrained users.
Maintain power tools. Check for misalignment or sticking of moving parts, breakage of
parts and any other condition that may affect the power tool’s operation. If damaged, have
the power tool repaired before use. Many accidents are caused by poorly maintained
power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to stick and are easier to control.
Use the power tool, accessories and tool bits etc., in accordance with these instructions
and in the manner intended for the particular type of power tool, taking into account the
working conditions and the work to be performed. Use of the power tool for operations
different from intended could lead to a hazardous situation.
4.5 Service
Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
5 PRECAUTIONS
5.1 Things to do
The compressor must be used in a suitable environment (well ventilated with an ambient
temperature of between +5°C and +40°C) and never in places affected by dust, acids,
vapors, explosive or flammable gases.
Always maintain a safety distance of at least 4 meters between the compressor and the
work area.
Any coloring of the belt guards of the compressor during painting operations indicates that
the distance is too short.
Insert the plug of the electric cable in a socket of suitable shape, voltage and frequency
complying with current regulations.
For three-phase versions have the plug fitted by a qualified electrician according to local
regulations. The first time you start the compressor, check that the direction of rotation is
correct and matches that indicated by the arrow on the conveyor (Fig. 1, the air must be
conveyed towards the head of the compressor).
Use extension cables with a maximum length of 5 meters and of suitable cross-section.
The use of extension cables of different length and also of adapters and multiple sockets
should be avoided.
Always use the switch of the pressure switch to switch off the compressor
Always use the handle to move the compressor.
When operating, the compressor must be placed on a stable, horizontal surface to
guarantee correct lubrication.
5.2 Things not to do
Never direct the jet of air towards persons, animals or your body. (Always wear safety
goggles to protect your eyes against flying objects that may be lifted by the jet of air).
Never direct the jet of liquids sprayed by tools connected to the compressor towards the
compressor.

POWX1790 EN
Copyright © 2017 VARO P a g e | 5www.varo.com
Never use the appliance with bare feet or wet hands or feet.
Never pull the power cable to disconnect the plug from the socket or to move the
compressor.
Never leave the appliance exposed to adverse weather conditions.
Never transport the compressor with the receiver under pressure.
Do not weld or machine the receiver. In the case of faults or rusting, replace the entire
receiver.
Never allow inexpert persons to use the compressor. Keep children and animals at a
distance from the work area.
Do not position flammable or nylon/fabric objects closed to and/or on the compressor.
Never clean the compressor with flammable liquids or solvents. Check that you have
unplugged the compressor and clean with a damp cloth only.
The compressor must be used only for air compression. Do not use the compressor for
any other type of gas.
The compressed air produced by the compressor cannot not be used for pharmaceutical,
food or medical purposes except after particular treatments and cannot be used to fill the
air bottles of scuba divers.
5.3 Things you should know
To avoid overheating of the electric motor, this compressor is designed for intermittent
operation as indicated on the technical dataplate (for example, S3-25 means 2.5 minutes
ON, 7.5 minutes OFF). In the case of overheating, the thermal cutout of the motor trips,
automatically cutting off the power when the temperature is too high. The motor restarts
automatically when normal temperature conditions are restored.
To facilitate restart of the compressor, in addition to the operations indicated, it is
important to return the button of the pressure switch to the OFF position and then to ON
again (figures 2-3-4).
On certain «V» type versions, the reset button on the terminal box of the motor must be
pressed (fig. 5).
On three-phase versions, simply return the button of the pressure switch to the ON
position. (fig. 3).
Single-phase versions are fitted with a pressure switch equipped with a delayed closing air
discharge valve which facilitates start-up of the motor. Therefore venting of air from this
valve for a few seconds with the receiver empty is normal.
All the compressors are fitted with a safety valve that is tripped in the case of
malfunctioning of the pressure switch in order to assure machine safety.
When fitting a tool, the flow of air in output must be switched off.
When using compressed air, you must know and comply with the safety precautions to be
adopted for each type of application (inflation, pneumatic tools, painting, washing with
water-based detergents only, etc.).
6 START-UP AND USE
Fit the wheels and foot (or the suckers according to model) following the instructions
provided in the packaging.
Check for correspondence between the compressor plate data with the actual
specifications of the electrical system. A variation of ± 10% with respect of the rated value
is allowed.
Insert the plug of the power cable in a suitable socket (fig. 6) checking that the button of
the pressure switch located on the compressor is in the OFF «O» position.
For lubricated models, check the oil level using the rod included in the oil fuel plug (figures
7a-7b-7c) or the sight glass (fig. 7d), and if necessary top up.
At this point, the compressor is ready for use.
Operating on the switch of the pressure switch (fig. 3), the compressor starts, pumping air
into the receiver through the delivery pipe.

POWX1790 EN
Copyright © 2017 VARO P a g e | 6www.varo.com
When the upper calibration value (set by the manufacturer) has been reached, the
compressor stops, venting the excess air present in the head and in the delivery pipe
through a valve located under the pressure switch. This facilitates subsequent restart due
to the absence of pressure in the head. When air is used, the compressor restarts
automatically when the lower calibration value is reached (2 bar between upper and
lower).
The pressure in the receiver can be checked on the gauge provided (fig. 8).
The compressor continues to operate according to this automatic cycle until the switch of
the pressure switch is turned.
Always wait at least 10 seconds from when the compressor has been switched off before
restarting this.
All compressors are fitted with a pressure reducer. Operating on the knob with the tap
open (pulling it up and turning it in a clockwise direction to increase the pressure and in a
counterclockwise direction to reduce this fig. 9a), air pressure can be regulated so as to
optimize use of pneumatic tools. After setting the value required, push the knob to fasten
this (fig. 9b). On some versions, the ring-nut underneath must be tightened to fasten the
knob (figures 9c-9d).
The value set can be checked on the gauge.
Please check that the air consumption and the maximum working pressure of the
pneumatic tool to be used are compatible with the pressure set on the pressure regulator
and with the amount of air supplied by the compressor.
Always pull out the plug and drain the receiver once you have completed your work
(figures 10-11).

9 MAINTENANCE
BEFORE CARRYING OUT ANY OPERATION, ALWAYS PULL OUT THE PLUG AND
DRAIN THE RECEIVER COMPLETELY (figures 10-11)
Check that all screws (in particular those of the head of the unit) are tightly drawn up
(torque 10 Nm = 1.02 Kgm). The check must be carried out prior to the first compressor
starting.

POWX1790 EN
Copyright © 2017 VARO P a g e | 7www.varo.com
After loosening any safety screws (fig. 12a), clean the intake filter according to the type of
working environment and at least every 100 hours (figures 12b-12c). If necessary, replace
the filter element (clogging of the filter reduces compressor performance and an inefficient
filter causes increased wear).
For lubricated models, replace the oil after the first 100 hours of operation and every 300
hours subsequently (figures 13a-13b-13c). Remember to check the oil level at regular
intervals. Use API CC/SC SAE 40. (For cold climates, API CC/SC SAE 20 is
recommended). Never mix different grade oils. If the oil changes color (whitish = presence
of water; dark = overheated), it is good practice to replace the oil immediately.
Periodically (or after working with the compressor for more than an hour), drain the
condensate that forms inside the receiver (fig. 11) due to the humidity in the air. This
protects the receiver from corrosion and does not restrict its capacity.
Spent oil (lubricated models) and condensate MUST BE DISPOSED OF in accordance
with environmental protection regulations and current legislation.
10 MAINTENANCE SCHEDULE
Cleaning of intake filter and/ or substitution of filtering element: every 100 hours
Change of oil: After the first 100 hours + every 300 hours
Tightening of head tension rods: The check must be carried out prior to the first
compressor starting
Draining tank condensate: Periodically and at the end of work
