EP12XS HR13
Too little oil in the pulse unit implies a high pulse
frequency and there will be a risk of a decreasing
tightening torque. In particular at the first tightening
after a break the machine might race.
Use Hydraulic Oil : 22 cST / 40 °C (ISO VG22).
Running the machine with too little oil may dam-
age the pulse unit.
After the refill – Check the tightening torque, see
Service instructions.
Rust protection and internal cleaning
Water in the compressed air, dust and wear particles
cause rust and sticking of vanes, valves etc. An air
filter should be installed close to the machine (se 'Air
quality'). Before longer standstills, flush with oil
(some drops) into the air inlet, run the machine for
5-10 seconds when absorbing the oil in a cloth.
Service instructions
Overhaul and preventive maintenance is recommen-
ded at regular intervals once per year or after maxim-
um 250.000 tightening depending on which occurs
sooner. More frequent overhaul may be needed,
specially replacing of oil in the pulse unit, if used at
high torque and long tightening times. If the machine
is not working properly, it should immediately be
taken away for inspection.
The strainer at the air inlet and the exhaust silencer
should be cleaned frequently or replaced in order to
prevent clogging, which decreases the capacity.
At the overhauls, all parts should be cleaned accur-
ately and defective or worn parts should be replaced.
A
All o-rings should be greased before assem-
bling; especially important are the o-rings in
the pulse unit.
Disassembling /assembling
It is important that the machines threaded connec-
tions are tightened properly; i.e. in accordance with
the specifications on the exploded views.
Cleaning
Clean all parts, not electrical, thoroughly in white
spirit or similar cleaning agent. To prevent clogging
and decreased power, it could be necessary to clean
the strainer (if used) and the exhaust filter between
the overhauls.
Inspection
After the cleaning, inspect all parts. Damaged and
worn parts should be replaced.
Lubrication
Lubricate specially gears, valve and clutch with
grease containing molybdenum disulphide (e.g.

Ergonomic guidelines
) Take frequent breaks and change work positions
1
frequently.
) Adapt the workstation area to your needs and the
2
work task.
• Adjust for convenient reach range by determin-
ing where parts or tools should be located to
avoid static load.
• Use workstation equipment such as tables and
chairs appropriate for the work task.
) Avoid work positions above shoulder level or with
3
static holding during assembly operations.
• When working above shoulder level, reduce
the load on the static muscles by reducing the
weight of the tool, using for example torque
arms, hose reels or weight balancers. You can
also reduce the load on the static muscles by
holding the tool close to the body.
• Make sure to take frequent breaks.
• Avoid extreme arm or wrist postures, particu-
larly for operations requiring a degree of force.
) Adjust for convenient field of vision by minimiz-
4
ing movement of the eyes and head during the
work task.
) Use the appropriate lighting for the work task.
5
) Select the appropriate tool for the work task.
6
) Use ear protection equipment in noisy environ-
7
ments.
