WARNING
Risk of injury and damage to material property because of improper handling!
 Hold the manual at the disposal of the operating sta at the usage site of the unit.
 Country-specic safety measures and accident prevention regulations must be
observed.
3. Intended conditions of use
The battery grease gun is ideally suited for mobile applications and is solely designed for pumping greases
up to NLGI 2. Operation with 20 Volt battery power.
The maximum permissible technical data must not be exceeded.
Any departure from the usage stipulations (other media, use of force) or unauthorized modications
(changes, use of non-original parts) can be dangerous and are considered to be non-intended usage.
The user is liable for any damage resulting from non-intended use.

Operating Instructions - Battery Grease Gun GB
3.1 Reasonably foreseeable misuse
Foreseeable misuse could be:
– Using the battery grease gun with a cartridge that is not conform to the DIN 1284 standard.
– Use greases that do not comply with the NLGI 2 viscosity class.
3.2 Design and functional description
The battery grease gun is powered by a lithium ion battery. It is driven by a small low-voltage electric mo-
tor which is connected to a gear drive.
The technology integrated in the battery grease gun includes the following:
1. A motor protection preventing an overload due to an excessive power consumption. In this case, the
motor stops and the display ashes red.
2. An LCD display indicating the battery charge, the delivery speed and the delivery volume.
3. An LED light to illuminate the lubricator / grease nipple.
4. A grease ow monitoring system and the indication of the delivery volume
The measurement accuracy for the delivery rate is +/- 10 % at ambient temperatures from 0°C to 35°C
and at counter pressures from 0 to 250 bar. Outside these parameters, accurate measurements of the
delivered volume are not possible. The accuracy of the measuring device applies for the use with
NLGI 2 grease, the resolution is 0.1 g.

5. Area of application
The grease gun is suitable for pressing greases up to the viscosity class NLGI 2 at a temperature of 20 °C.
6. Risks when handling the battery grease gun
CAUTION
Excessive pressure at the point of lubrication may destroy the grease
nipple, the bearing or even the machine
 Observe the maintenance and service instructions of the machine
manufacturer.
CAUTION
Damaged accessories may lead to personal injury and material damage!
 High pressure hoses must not be bent, twisted or stretched.
 Attachments and accessories must be checked for wear, splits or other
damage throughout its period of use.
 Damaged accessories and attachments must be replaced immediately.
DANGER
 Never work with the battery grease gun in the vicinity of open re, gas or
other combustible uids.
 The battery grease gun can build up a high pressure (up to 400 bar). Safety
glasses and safety shoes are required. Keep hands away from rubber hoses
under high pressure.
CAUTION
Risk of personal injury due to electric shock!
 Avoid contact with other metals during greasing because of the risk of
accidental earthing.
 Do not use the device in rain or when wet (electric shock!).
 Do not use the battery charger in humid / moist rooms.
 Do not use the grease gun if it is damaged, if it was stored under the open sky
or if it was dipped into a liquid.
7. Commissioning and putting into operation
 Check the grease gun and the accessories for completeness (see achapter 12.
exploded view of the battery grease gun).
 After each relling or grease cartridge change, check the grease gun. Note that an air bubble may
cause fat loss or ineciency.
Use the venting valve to vent the grease pump (see achapter 7.1.4.).

GB Operating Instructions - Battery Grease Gun
7.1 Filling the grease gun
There are various possibilities to ll the grease gun:
– Filling with grease cartridge according to DIN 1284.
– Filling with grease gun lling device by lling nipple.
– Filling with bulk grease from a large container.
7.1.1. Filling with grease cartridge according to DIN 1284
Removing an empty cartridge:
CAUTION
Injuries due to overpressure
 Do not open the grease gun under pressure!
 Before disconnecting the grease gun head and tube, the push rod must be
pulled back and locked automatically by the locking pawl.
 Unscrew the grease gun tube from the device.
 Slowly loosen the handle, pull the grease cartridge up and out of the device.
Installing a new grease cartridge:
 Remove the plastic cap from the full grease cartridge and insert it into the grease gun tube.
 Only then tear o the„pull-o“ closure of the cartridge and screw up the grease gun head.
 While pulling on the push rod, activate the locking pawl and slide the push rod back into the tube.
 Use the venting valve to bleed o any air that may be trapped in the cartridge
(see achapter 7.1.4.).
NOTE
 Ensure cleanliness during installation and that the accessories are correctly
connected with the grease gun head.
 Use appropriate sealants and adhesives (e. g. Teon tape).
7.1.2. Filling with grease gun lling device
 Put the grease gun with the lling nipple on the lling valve of the grease gun lling device and hold it
with light counter pressure.
 Actuate the grease gun lling device to ll the grease gun. The push rod may be pressed out of the
grease gun tube by the lling operation.
 While pulling on the push rod, activate the locking pawl and slide the push rod back into the tube.
7.1.3. Filling the grease gun from a bulk container
 Unscrew the grease gun tube from the grease gun.
 Plunge the open end of the grease gun tube into the grease container.
 Hold the grease gun tube and slowly pull the piston back by means of the grip.
Ensure that the open end of the grease gun tube is always completely immersed in the grease in order
to avoid the intake of air.
 Stop lling when the piston is completely pulled out.
 Screw the grease gun tube down again to the head of the grease gun.
 While pulling on the push rod, activate the locking pawl and slide the push rod back into the tube.
7.1.4. Removal of trapped air
 Use the venting valve to vent the grease pump.
 Vent the grease gun, open the venting valve until grease escapes from the venting valve.
 Close the venting valve.
 Press the trigger until grease escapes from the precision machined coupler.

7.2 Making the grease gun ready for operation
Check to ensure that the grease gun tube is tightly screwed in the device. To remove trapped air, open the
venting valve while the push rod is moved forward. The grease gun is now ready for operation.
Switching on the display and the LED light:
Switching on the display:
Press button 1 or operate the trigger/switch.
Switching on/o the LED light:
Press button 1.
After the greasing operation, the display and the LED light are turned o automatically
after 30 seconds.
Selection of the pump speed
Press button 2 to switch between high and low pump speed. The letters„L“ (low speed) or„H“ (high speed)
appear on the screen.
140 g/min are delivered at high speed (H) and at a counter pressure of 100 bar.
95 g/min are delivered at low speed (L) and at a counter pressure of 100 bar.
The motor speed automatically switches from L to H, if the counter pressure exceeds 200 bar.
Resetting the counted delivery volume (Pos. 3, g.)
Keep button 1 pressed for 3 seconds in order to reset the indicated delivery volume to 0.
Switching the unit of measurement (Pos. 4, g.)

8. Battery
The battery is only partially charged at delivery. When used for the rst time, it must be fully charged
to ensure satisfactory performance. When the tool performance begins to drop sharply, it indicates the
battery needs to be recharged.
NOTE
 Only use the supplied charger. Other chargers may catch re and are not
suitable for this device.
 Avoid that the battery is completely discharged when the current level is low,
because otherwise the battery‘s lifetime will be considerably reduced.
Charging process
 Connect the charger to an appropriate socket before inserting the battery.
 Put the battery on the charger. Check to ensure that the battery and the charger are completely connected.
When the battery is fully secured, a faint„click“ can be heard.
 Press the selection button in order to display the charging status on the screen. If the battery is fully
charged, the display remains switched on.
 When the battery is completely charged (approx. 60 minutes), disconnect the charger from the mains and
take out the battery.
