Bosch Power Tools 1 609 92A 0KR | (26.5.14)

Work area safety

 Keep work area clean and well lit. Cluttered 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. Distractions can cause you to lose control.

Electrical safety

 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.

 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 unplugging the power tool. Keep cord away
from heat, oil, sharp edges and moving parts. Damaged

or entangled cords increase the risk of electric shock.

 When operating a power tool outdoors, use an exten-

sion 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 unavoid-

able, use a residual current device (RCD) protected
supply. Use of an RCD reduces the risk of electric shock.

Personal safety

 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 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 protection
used for appropriate conditions will reduce personal inju­ries.

 Prevent unintentional starting. Ensure the switch is in

the off-position 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 ro-

tating 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

unexpected situations.

 Dress properly. Do not wear loose clothing or jewel-

lery. Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewellery or long hair can be

caught in moving parts.

 If devices are provided for the connection of dust ex-

traction and collection facilities, ensure these are con­nected and properly used. Use of dust collection can re-

duce dust-related hazards.

Power tool use and care

 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.

 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

starting 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

tools are dangerous in the hands of untrained users.

 Maintain power tools. Check for misalignment or bind-

ing 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 cuttin g edges are less likely to bind
and are easier to control.

 Use the power tool, accessories and tool bits etc. in ac-

cordance with these instructions, 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.

Service

 Have your power tool serviced by a qualified repair per-

son using only identical replacement parts. This will en-

sure that the safety of the power tool is maintained.

Safety Warnings for Jigsaws

 Hold power tool by insulated gripping surfaces, when

performing an operation where the cutting accessory
may contact hidden wiring or its own cord. Cutting ac-

cessory contacting a “live” wire may make exposed metal
parts of the power tool “live” and could give the operator an
electric shock.

Additional Safety and Working
Instructions

 Keep hands away from the sawing range. Do not reach

under the workpiece. Contact with the saw blade can

lead to injuries.

 Apply the machine to the workpiece only when

switched on. Otherwise there is danger of kickback when

the cutting tool jams in the workpiece.

 Pay attention that the base plate rests securely on the

material while sawing. A jammed saw blade can break or

lead to kickback.

 When the cut is completed, switch off the machine and

then pull the saw blade out of the cut only after it has
come to a standstill. In this manner you can avoid kick-

back and can place down the machine securely.

 Use only undamaged saw blades that are in perfect con-

dition. Bent or dull saw blades can break, negatively influ-

ence the cut, or lead to kickback.

 Do not brake the saw blade to a stop by applying side

pressure after switching off. The saw blade can be dam-

aged, break or cause kickback.

 Use suitable detectors to determine if utility lines are

hi dden in t he wo rk a rea o r call the local utility company
for assistance. Contact with electric lines can lead to fire

and electric shock. Damaging a gas line can lead to explo­sion. Penetrating a water line causes property damage or
may cause an electric shock.

 Secure the workpiece. A workpiece clamped with clamp-

ing devices or in a vice is held more secure than by hand.

 Always wait until the machine has come to a complete

stop before placing it down. The tool insert can jam and

lead to loss of control over the power tool.

 Before any work on the machine itself, pull the mains

plug.

 The saw blade should not be longer than required for

the intended cut. Use a narrow saw blade when sawing
tight curves.

 Check the tight seating of the saw blade. A loose saw

blade can fall out and lead to injuries.

 When ejecting the saw blade, hold the machine in such

a manner that no persons or animals can be injured by
the ejected saw blade.

 Dusts from materials such as lead-containing coatings,

some wood types, minerals and metal can be harmful to
one’s health and cause allergic reactions, lead to res­piratory infections and/or cancer. Materials containing

asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable

for the material.

– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the
materials to be worked.

 Prevent dust accumulation at the workplace. Dusts can

easily ignite.

 Observe correct mains voltage! The voltage of the pow-

er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.

 To s ave e nerg y, on ly sw itch the p ower tool on wh en u sing i t.
 The contact protector attached to the casing (see fig-

ure 14, page 191) prevents accidental touching of the
saw blade during the working procedure and may not
be removed.

 Before sawing in wood, particle boards, building mate-

rials etc., check for foreign objects, such as nails,
screws, etc. and remove them as required.

 Plunge cuts may only be applied to soft materials, such

as wood, gypsum board, etc. For plunge cuts, use only
short saw blades.

 The splinter guard can prevent fraying of the surface

while sawing wood. Do not use the splinter guard for
mitre cuts.

 Adapt the settings of your power tool to the respective

application. For example, reduce the stroke rate and
orbital action when cutting metal or for tight curved
cuts.

 When working small or thin work pieces, always use a

sturdy support or a saw table (accessory).

 In extreme conditions, always use dust extraction as

far as possible. Blow out ventilation slots frequently
and install a residual current device (RCD). When work-

ing metals, conductive dust can settle in the interior of the
power tool. The total in sulation of the power tool can be im­paired.

 Products sold in GB only: Your product is fitted with a

BS 1363/A approved electric plug with internal fuse
(ASTA approved to BS 1362).
If the plug is not suitable for your socket outlets, it should
be cut off and an appropriate plug fitted in its place by an
authorised customer service agent. The replacement plug
should have the same fuse rating as the original plug.
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains
socket elsewhere.
Products sold in AUS and NZ only: Use a residual current
device (RCD) with a rated residual current of 30 mA or
less.

Noise/Vibration Information

The measured values of the machine are listed in the table on
page 182.

Sound emission values determined according to
EN 60745-2-11.

Vibration total values a

h

(triax vector sum) and uncertainty K

determined according to EN 60745.
The vibration level given in this information sheet has been

measured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with anoth­er. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main ap­plications of the tool. However if the tool is used for different
applications, with different accessories or insertion tools or is
poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total
working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig­nificantly reduce the exposure level over the total working
period.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work pat­terns.

Mounting and Operation

The following table indicates the action objectives for mounting and operation of the power tool. The instructions for each action
objective are shown aside. Depending on the type of application, various instruction combinations are required. Observe the
