eyes, or to remain on your skin may promote

absorption of harmful chemicals.

6.2.2 Power tool use and care

a) Secure the workpiece. Use clamps or a vice

to secure the workpiece. The workpiece is thus

held more securely than by hand and both hands

remain free to operate the power tool.

b) Check that the insert tools used are compatible

with the chuck system and that they are secured

in the chuck correctly.

6.2.3 Special safety instructions for

reciprocating saws

a) Always guide the power tool away from your

body when working with it.

b) Never position your hands ahead of or on the

saw blade.

c) Never cut into unknown materials and keep the

line of cut above and below the workpiece free

of obstacles. If the saw blade strikes an object it

may cause the power tool to kick back.

d) Apply moderate pressure and set the power tool

to a suitable stroke rate when using the pipe-

cutting adapter (accessory), especially when

cutting large-diameter pipes. This will help to

prevent the power tool overheating.

e) The power tool must be pressed against the

workpiece until the AVR contact shoe makes

firm contact. This helps ensure maximum safety

and good performance.

f) Wear suitable protective clothing to protect you

from hot cuttings.

g) Never use the power tool without a fully func-

tional hand guard.

h) Before beginning the work, check the hazard

classification of the dust that will be produced.

Use an industrial vacuum cleaner with an offi-

cially approved protection classification in com-

pliance with locally applicable dust protection

regulations.

i) WARNING!When cutting through pipes, e.g.

when carrying out demolition or installation

work, check to ensure that the pipes no longer

contain liquids and empty them if necessary.

When cutting through pipes, hold the power

tool above the level of the pipe you are cut-

ting through. The power tool incorporates no

protective measures to prevent ingress of water

or dampness. Liquids running out of pipes may

cause a short circuit in the power tool.

j) Do not use the power tool to cut bricks, concrete,

cellular concrete, natural stone or tiles.

k) Do not attempt to cut material thicker than the

specified max. thickness for which the saw is

designed and do not use unsuitable saw blades

(reciprocating saw blades of the wrong size or

not equipped with a ¹⁄₂" connection end).

l) The transport lock should always be engaged

when the power tool is not in use.

6.2.4 Battery tool use and care

a) Observe the special instructions applicable to

the transport, storage and use of Li-ion batter-

ies.

b) Do not expose batteries to high temperatures or

fire. This presents a risk of explosion.

c) Do not disassemble, squash or incinerate bat-

teries and do not subject them to temperatures

over 80°C. A risk of fire, explosion or injury

through contact with caustic substances may

otherwise result.

d) Do not use batteries other than those approved

for use with the applicable power tool or appli-

ance. Use of other batteries or use of the battery

for purposes for which it is not intended presents

a risk of fire and explosion.

e) Do not charge or continue to use damaged bat-

teries (e.g. batteries with cracks, broken parts,

bent or pushed-in and/or pulled-out contacts).

f) Use only the Hilti chargers listed under “Acces-

sories”.

g) Ensure that the outer surfaces of the battery

are clean and dry before inserting it in the

corresponding charger. Read the operating in-

structions for the charger for further information

about the charging procedure.

6.2.5 Electrical safety

Before beginning work, check the working area

(e.g. using a metal detector) to ensure that no

concealed electric cables or gas and water pipes

are present. External metal parts of the power tool

may become live, for example, when an electric cable

is damaged accidentally. This presents a serious risk

of electric shock.
