Safety Notes
General Power Tool Safety Warnings
WARNING! Read all safety warnings, instructions, illustrations and
specifications provided with this power tool.
Failure to follow all instructions listed below 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 electrically operated
(corded) power tool or battery-operated (cordless) power tool.
Work area safety
- 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.
Electrical safety
- 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 and moving parts. Damaged or entangled cords increase the risk of electric shock.
- When operating a power tool outdoors only, use extension cords 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.
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 momentary lack of attention while operating power tools may result in serious personal injury.
- Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
- Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising 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 dust collection can reduce dust-related hazards.
- Do not let familiarity gained from frequent use of tools allow you to become compla-cent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
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 and/or remove the battery pack, if detachable, from the power tool 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 and accessories. Check for misalignment or binding 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 bind and are easier to control.
- Use the power tool, accessories and tool bits etc., in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
- Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

Set-up of pump before first operation
Pump is supplied without oil charge; before initial operation, it is
mandatory to fill the pump with the recommended oil charge.
Filling of oil
Pump must be turned off for filling the oil and level control.
Pump is supplied with a mineral oil bottle but without oil charge inside the
vacuum pump; before initial operation, it is mandatory to fill the pump with
the oil up to the indicated oil level in the oil level sight glass. Only use
ROTHENBERGER oil; different lubricants reduce performance and may cause
irreversible damage to the pump. Warranty is void if other oil has been used.
For fill-up proceed as follows:
- Unscrew charging plug (placed on upper part of pump)
- Slowly add the oil until middle of sight glass has been reached (indicated by MAX MIN line)
- Screw-on the plug again
To avoid excessive filling, it is suggested to only add the oil with a graduated recipient; in that way it is easy to check the added volume. In case of excessive filling, it is necessary to completely empty the pump and repeat the oil filling procedure.
WARNING: Do not pollute the environment by spilling oil; the lubricant oil is a special waste and must be disposed of according to relevant local law/guidelines in force.
Connection for evacuation
Shorter hose length or wider ID, as well as straight path, reduce the
evacuation time as the pump will reach the desired vacuum more quickly. To
prevent backflow of lubricant from the pump into the evacuated system in case
of unexpected power failure, a solenoid non-return valve is provided at the
suction connection.
Power Supply
Always check the power supply; it has to comply with the data on the rating
label on the pump. The pumps’ motor is equipped with a thermal overload
protection with automatic reset and cuts off power supply at +130°C / +266°F.
General Precautions
The pumps’ motor must always be suitably grounded. The pump temperature is not
expected to rise to a very high level during operation; however it is
advisable to locate the unit in such a way that no contact can be made, as it
may cause burns. When using the pump with other equipment, it must be ensured
that the pump is fixed properly and safe to use for the operator. The vacuum
pump is air-cooled by a built-in fan; only use it where the air can freely
circulate and keep it away from walls or obstacles no less than 2” (5 cm). Do
not cover the pump during operation.
Operation
To guarantee reliability and high level of quality, each pump is subjected to a rigorous testing and suitable preliminary running in before it leaves the factory. Constant performance and long operating life are assured by strictly observing the following procedures:
Pump start
Before the first initial run, it is mandatory to:
- Fill the pump with the provided oil (see section “filling of oil”).
- Before subsequent start-ups, always check the oil level before starting the pump. If necessary, top-up or replace the oil.
- Before connecting the pump to the system to be evacuated, check that there is no pressure inside. In case of connecting the pump with a pressurized system, the vacuum gauge may break. The vacuum gauge measures negatives pressures and get collapsed with positive pressures. Warranty is void if the pump is connected to a positive pressure.
- Connect the pump to the system to be evacuated by the necessary equipment (quality hos-es, quality manifolds, etc). The evacuation quality will be directly related to the way of connection and to the equipment quality.
In case of malfunctioning, stop the pump and call the Service- After-Sales.
Pump stop
As the mixture of incompatible lubricants (pump oil and compressor oil) can
lead to pump failure, installing a solenoid non-return valve at the suction
connection is required (provided). In case of frequent on-off cycling, do not
stop the pump but shut-off at the charging hose or manifold in-stead.
Routine maintenance
Periodic and correct maintenance of the vacuum pump will ensure a long operation life and con-stant performance.
Lubrication
The oil provided with the pump has been specially formulated & manufactured to
lubricate vacu-um pumps; it is special as it features minimum viscosity
fluctuation when in use under a wide temperature range.
The type of lubricant supplied with the pump allows the evacuation of systems
operating refrig-erants. Only working with ROTHENBERGER POE synthetic oil.
The required amount of lubricating oil depends on the size of the pump
container specified in the section “Technical data” and must correspond to the
quantity required until the dimensions of the sight glass are reached.
Replace the oil charge no later than 20 hours of operation.
Oil could be polluted by other oil, humidity, refrigerants, etc. It is
mandatory to use oil in perfect conditions to assure a perfect performance of
the pump.
Oil-change
Over-used lubrication oil damages the pumps’ mechanism; make sure to replace
oil as soon as it starts to turn cloudy. For conducting the oil-change, the
pump must be switched off. For changing the oil proceed as follows:
- Unscrew the oil drainage plug located on the lower part of the pump
- Check that oil comes out completely from the pump
- Tightly screw the oil drainage plug back on
- Re-fill the pump with oil (see “Filling of oil”)
WARNING: Do not pollute the environment by spilling oil; the lubricant oil is a special waste and must be disposed of according to relevant local law / guidelines in force.
Extraordinary maintenance/repair
Conduct extraordinary maintenance or repair whenever serious faults occur such
as overheating, poor ultimate vacuum, persistent loudness / noise, blocked
pump or any other irregular functioning.
In that case, the pump needs to be disassembled, parts need to be cleaned,
repaired or replaced.
Only qualified service staff shall carry out such maintenance or repair work;
otherwise the warranty will be void.
