GENERAL SAFETY RULES GEA002-3

WARNING:

Read all instructions. Failure to follow all instructions listed below may result in

electric shock, fire and/or serious injury. The term “power tool” in all of the
warnings listed below refers to your mains-operated (corded) power tool or battery­operated (cordless) power tool.

SAVE THESE INSTRUCTIONS.

Wor k a rea sa fet y

1. Keep work area clean and well lit. Cluttered and

dark areas invite accidents.

2. Do not operate power tools in explosive atmo-

spheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks

which may ignite the dust or fumes.

3. Keep children and bystanders away while oper-

ating a power tool. Distractions can cause you to

lose control.

Electrical safety

4. 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.

5. 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.

6. Do not expose power tools to rain or wet condi-

tions. Water entering a power tool will increase the

risk of electric shock.

7. 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.

8. 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.

Person al safety

9. 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.

10. Use safety equipment. Always wear eye protec­tion. Safety equipment such as dust mask, non-skid

safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal inju­ries.

11. 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.

3

12. 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.

13. Do not overreach. Keep proper footing and bal­ance at all times. This enables better control of the

power tool in unexpected situations.

14. 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.

15. 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.

Power tool use and care

16. 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.

17. 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.

18. 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 starting the power tool
accidentally.

19. 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.

20. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tools operation. If damaged, have the power tool
repaired before use. Many accidents are caused

by poorly maintained power tools.

21. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.

22. 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 those
intended could result in a hazardous situation.

Battery tool use and care

23. Ensure the switch is in the off position before
inserting battery pack. Inserting the battery pack

into power tools that have the switch on invites acci­dents.

4

24. Recharge only with the 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.

25. Use power tools only with specifically desig­nated battery packs. Use of any other battery

packs may create a risk of injury and fire.

26. 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 terminals together

may cause burns or a fire.

27. Under abusive conditions, liquid may be ejected
from the battery, avoid contact. If contact acci­dentally occurs, flush with water. If liquid con­tacts eyes, additionally seek medical help. Liquid

ejected from the battery may cause irritation or
burns.

Service

28. 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.

29. Follow instruction for lubricating and changing
accessories.

30. Keep handles dry, clean and free from oil and
grease.

CAUTION:

• Always be sure that the tool is switched off and the battery cartridge is
removed before adjusting or checking function on the tool.

Installing or removing battery cartridge

• Always switch off the tool before insertion or removal of the battery
cartridge.

• To remove the battery cartridge, first open the battery cartridge cover. To
open the cover, press its recessed part and pivot it with the recessed part
depressed. And then withdraw it from the tool while sliding the button on
the front of the cartridge.

• To insert the battery cartridge, align the tongue on the battery cartridge
with the groove in the housing and slip it into place. Always insert it all the
way until it locks in place with a little click. If you can see the red part on
the upper side of the button, it is not locked completely. Insert it fully until
the red part cannot be seen. If not, it may accidentally fall out of the tool,
causing injury to you or someone around you.

• Do not use force when inserting the battery cartridge. If the cartridge
does not slide in easily, it is not being inserted correctly.

Switch action

CAUTION:

1

• Before inserting the battery cartridge into the tool, always check to see
that the switch lever actuates properly and returns to the “OFF” position
when released.

To start the tool, simply pull the switch lever. Release the switch lever to stop.
Switch lever can be pulled from either top or back side of the tool.

Hold the tool straight when inserting/operating. Use the tool within the effective
vibrations range at equidistant intervals. The effective air bubble removal
range is about ten times diameter of the vibrating head, or around 250 mm.
Do not use this tool to move concrete within a form. The mortar will just move
away and the coarse aggregate will remain, causing segregation.

Effective leveling and removal of air bubbles

Removal of the air bubbles is complete after you have worked the tool through­out each effective range, the concrete stops shrinking, and the mortar has
risen evenly to the surface, giving off a light appearance. Gently remove the
operating tool not to leave holes.

NOTE:

• Vibrating too long in a single place causes concrete segregation.

• When the coarse aggregates segregates when placing concrete, shovel

out the coarse aggregate and put it where there is plenty of mortar. Then
use the tool on it. Don’t leave coarse aggregate in the segregated
condition.

When concreting a slope site, always pour from the bottom at the beginning.

001961

This way the weight of the freshly poured concrete and vibration will lead to
effective removal of air bubbles. Conversely, if the pouring is done first from
above, the mortar will separate and eventually slide to the bottom.
