General power tool
safety warnings
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.
Work area safety
• Keep work area clean and well lit. Clut-
tered or 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. Distrac-
tions can cause you to lose control.
Electrical safety
• Power tool plugs must match the out-
let. 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 unplug-
ging 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 out-
doors, 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 sup-
ply. Use of an RCD reduces the risk of
electric shock.
Personal safety
• Stay alert, watch what you are doing
and use common sense when operat-
ing a power tool. Do not use a power
tool while you are tired or under the
influence of drugs, alcohol or medica-
tion. A moment of inattention while op-
erating 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 protec-
tion used for appropriate conditions will
reduce personal injuries.
• Prevent unintentional starting.
Ensure the switch is in the off-posi-
tion 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 rotat-
ing 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 unex-
pected 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.
Read all safety warnings and
instructions. Failure to follow
the warnings and instructions
may result in electric shock,
fire and/or serious injury.
WARNING
• If devices are provided for the connec-
tion of dust extraction and collection
facilities, ensure these are connected
and properly used. Use of these devices
can reduce dust-related hazards
Power tool use and care
• Do not force the power tool. Use the
correct power tool for your applica-
tion.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 the battery pack from
the power tool before making any
adjustments, changing accessories, or
storing power tools. Such preventive
safety measures reduce the risk of start-
ing 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 tool is dangerous in
the hands of untrained users.
• Maintain power tools. 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 and in the manner in-
tended for the particular type of pow-
er tool, taking into account the work-
ing conditions and the work to be
performed. Use of the power tool for op-
erations different from those intended
could result in a hazardous situation.
Intended use
The SKF battery driven grease gun
TLGB 20 was exclusively designed to pump
and dispense lubricant using 20 V battery
power. Do not exceed the maximum specifi-
cation ratings.

Battery tool use and care
• Recharge only with the battery charger
specified by the manufacturer.
A charger that is suitable for one type of
battery pack may create a risk of fire
when used with another battery pack.
• Use power tools only with specifically
designated battery packs. Use of any
other battery packs may create risk of in-
jury and fire.
• When battery pack is not in use, keep
it away from other metal objects, like
paper clips, coins, keys, nails, screws
or other small metal objects, that can
make a connection from one terminal
to another. Shorting the battery termi-
nals together may cause burns or a fire.
• Under abusive conditions, liquid may
be ejected from the battery; avoid
contact. Liquid ejected from battery
may cause irritation or burns. If con-
tact accidentally occurs, flush with
water. If liquid contacts eyes, seek
medical help. Liquid ejected from the
battery may cause irritation or burns.
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 .
Specific safety
Use only SKF TLGB 20-3 high pressure hose
900 mm (36 in.) with coupler. Grease injec-
tion injuries are a very serious injury. Hold
the hose only in the area of the spring
guard. Avoid accidental starting. Be sure
switch is not pressed when inserting battery
pack.
Replace the hose at the first sign of wear,
kink or damage to the outside jacket. Do not
bend the hose so that it becomes kinked.
Do not overreach. Keep proper footing
and balance at all times. Proper footing and
balance enable better control of the tool in
unexpected situations.
Use safety equipment. Always wear eye
protection.
Dust mask, non-skid safety shoes, hard
hat or hearing protection must be used for
appropriate conditions.
The gun uses lubricants, that may be
flammable and poisonous if ingested. Do not
use gun near open flame or other fire haz-
ards. Do not use flammable greases with
this grease gun.
Grease is often marketed as high temper-
ature because it must maintain its lubricat-
ing properties in hot areas, but the lubricant
may be flammable if the temperature is too
high. Please read all warnings on lubricants
before using this gun.
Do not use flammable greases with this
grease gun.
Residual risks
Additional residual risks may arise when us-
ing the tool which may not be included in
the enclosed safety warnings. These risks
can arise from misuse, prolonged use etc.
Even with the application of the relevant
safety regulations and the implementation
of safety devices, certain residual risks can
not be avoided.
These include:
• Injuries caused by touching any rotating/
moving parts.
• Injuries caused when changing any parts,
accessories.
• Injuries caused by prolonged use of a tool.
When using any tool for prolonged peri-
ods ensure you take regular breaks.
• Impairment of hearing.
• Health hazards caused by breathing dust
developed when using your tool (example:
-working with wood, especially oak, beech
and MDF.)
Do not use any hose that has not been
approved by SKF. Extreme pressure may
cause nozzle extension or whip hose to
burst.
Replace hose at first sign of wear,
kinks, or damage to outside jacket.
Follow whip hose instructions and
warnings. Failure to comply may result
in serious injury or death.
WARNING
Grease gun can develop high pressure
up to 700 bar (10 000 psi). Use safety

SKF battery driven grease gun TLGB 20
General description
The SKF TLGB 20 is a lithium-ion battery
operated grease gun and was developed for
manual lubrication of grease points including
a light emitting diode (LED) and electronic
control center.
The SKF battery driven grease gun is
driven by a small, low voltage electric
motor connected to a gear transmission.
The rotary motion of the motor is converted
into a reciprocating motion of the plunger
using a yoke mechanism. The SKF battery
driven grease gun is a positive displacement
single acting pump.
Technology incorporated into the TLGB
20 includes:
• Motor protection preventing overload due
to excessive current draw. The display will
flash red when this occurs.
• An LCD showing battery charge, pump
speed and grease output.
• An illuminating LED to help locate grease
fittings in dim light.
Inspection
Visually inspect for damaged, loose or
missing parts. If equipment is worn or dam-
aged, remove from service. Contact an
authorized service center for damage
assessment or repair.

Charger operation
Charging battery pack
Before using your SKF Battery Driven
Grease Gun for the first time, the battery
pack should be fully charged. If the battery
pack is installed in the grease gun, remove it
and follow charging procedure.
SKF chargers are designed to charge SKF
lithium-ion batteries in 30 to 90 minutes
depending on the battery’s state of charge
and temperature.
Charging procedure
Make sure power circuit voltage is the same
as shown on the charger specification plate.
1 Plug the charger into an appropriate out-
let before inserting battery pack.
2 Insert the battery pack into the charger.
The green (charging) light will blink con-
tinuously indicating that the charging
process has started.
3 The completion of charge will be indicated
by the green light remaining on continu-
ously. The pack is fully charged and may
be used at this time.
4 Disconnect charger from power source
when not in use.
Important charging notices
Longest life and best performance can be
obtained if the battery is charged when the
air temperature is between 18 and 24 °C
(65 and 75 °F). Do not charge the battery in
an air temperature below 5 °C (40 °F) or
above 40 °C (105 °F). This is important and
will prevent serious damage to the battery.
1 The charger and battery may become
warm to the touch while charging. This is
a normal condition, and does not indicate
a problem.
2 If the battery does not charge properly:
2.1 Check current at receptacle by plug-
ging in a lamp or other appliance.
2.2 Check to see if the receptacle is con-
nected to a light switch which turns
power off when you turn out the
lights.
2.3 Move charger and battery to a loca-
tion where the surrounding air
temperature is between approxi-
mately 18 and 24 °C (65 and 75 °F).
2.4 If charging problems persist, take the
tool, battery and charger to your local
service center.
3 The battery should be recharged when it
fails to produce sufficient power on jobs.
Do not continue to use under these con-
ditions. Follow the charging procedure.
You may also charge a partially used pack
whenever you desire with no adverse
affect on the battery.
Do not probe with conductive objects.
120/230 V AC present at charging ter-
minals. Failure to comply may result in
death or personal injury.
CAUTION
........
-.-.-
!Notice
Battery temperature will increase
during and shortly after use. Batteries
may not accept a full charge if they are
charged immediately after use. Allow the
battery pack to cool to room tempera-
ture before charging for best results.
!Notice
Vent slots in top and bottom of
charger must not be obstructed. Do not
charge battery when temperature is be-
low 5 °C (40 °F) or above 40 °C (104 °F).
Do not allow any liquid to get inside
charger. Electric shock may result.
To facilitate cooling of battery pack
after use, avoid placing charger or bat-
tery pack in a warm environment such
as a metal shed or an non-insulated
trailer.
Failure to comply may result in seri-
ous injury or death.
WARNING
4 Under certain conditions, with the
charger plugged into the power supply,
the exposed charging contacts of the
charger can be shorted by foreign mate-
rial. Foreign materials of a conductive
nature such as, but not limited to, steel
wool, aluminium foil, or any buildup of
metallic particles should be kept away
from charger cavities. Always unplug the
charger from the power supply when
there is no battery in the cavity. Unplug
charger before attempting to clean.
