Safety Notes

General Power Tool Safety Warnings

Read all safety warnings and all instruc­tions. Failure to follow the warnings and

instructions may result in electric shock, fire and/or serious
injury.

Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your mains­operated (corded) power tool or battery-operated (cordless)
power tool.

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.

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 cutting 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 Sabre Saws

 Hold power tool by insulated gripping surfaces, when

performing an operation where the cutting accessory

Product Description and
Specifications

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.

 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.

 When sawing, the adjustable footplate 2 must always

faces against the workpiece. The saw blade can become

wedged and lead to loss of control over the machine.

 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 sharp, flawless saw blades. Bent or unsharp

saw blades can break or cause 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.

 Clamp material well. Do not support the workpiece

with your hand or foot. Do not touch objects or the floor
with the the saw running. Danger of kickback.

 Use suitable detectors to determine if utility lines are

hidden in the work area or 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.

 When working with the machine, always hold it firmly

with both hands and provide for a secure stance. The

power tool is guided more secure with both hands.

 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.

 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.

Intended Use

Assembly

Replacing/Inserting the Saw Blade

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

plug.

 When mounting the saw blade, wear protective gloves.

Danger of injury when touching the saw blade.

 When changing the saw blade, take care that the saw

blade holder is free of material residue, e. g. wood or
metal shavings.

Selecting a Saw Blade

An overview of recommended saw blades can be found at the
end of these instructions. Use only ½" universal shank saw
blades. The saw blade should not be longer than required for
the intended cut.

The shank thickness of the saw blade must be 0.8–1.6 mm.
Use a thin saw blade for narrow curve cuts.

Inserting the Saw Blade (see figure A)

Press the SDS clamping lever 4 forward and guide the saw
blade 1 behind the clamping plate 10 into the saw blade hold­er 3. Release the SDS clamping lever 4.

 Check the tight seating by pulling on the saw blade. A

loose saw blade can fall out and cause injury.

For certain work, the saw blade 1 can also be turned through
180° (with the teeth pointed upwards) and re-inserted again.

Removing the Saw Blade (see figure A)
 Before removing, allow the saw blade to cool down.

Danger of injury when touching the hot saw blade.

Press the SDS clamping lever 4 forward and pull out the saw
blade 1. Release the SDS clamping lever 4.

Dust/Chip Extraction

 Dusts from materials such as lead-containing coatings,

some wood types, minerals and metal can be harmful to
one’s health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat­ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– 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.

Operation

Operating Modes

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

plug.

Orbital Action Settings

The adjustable orbital action allows for optimal adaptation of
cutting speed, cutting capacity and cutting pattern to the ma­terial being worked.

The level of orbital action can be set with rotary switch 6, even
during operation.

Pivoting and Retractable Footplate (see figure B– C)

Due to its movability, the adjustable footplate 2 adapts to the
required angular position of the surface.

Depending on the application and the saw blade being used,
the footplate 2 can be moved variably in length direction.
Loosen the screws 11 with Allen key and move the footplate
2 to the requested position. Tighten the screws 11 again and
check if the footplate 2 is tightly seated.

Starting Operation

 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.

The stand by indicator 8 lights up when the mains plug is
plugged in and mains voltage is available. When the machine
cannot be started even though the stand by indicator is lit, it
must be taken to an authorized after-sales service agent for
Bosch power tools.

Switching On and Off

To start the machine, press the On/Off switch 7 and keep it
pressed.

To switch off the machine, release the On/Off switch 7.
Note: For safety reasons, the On/Off switch 7 cannot be

locked; it must remain pressed during the entire operation.

Controling the Stroke Rate

Increasing or reducing the pressure on the On/Off switch 7
enables stepless stroke-rate control of the switched-on ma­chine.

Light pressure on the On/Off switch 7 results in a low stroke
rate. Increasing the pressure also increases the stroke rate.

The required stroke rate is dependent on the material and the
working conditions and can be determined by a practical trial.

Reducing the stroke rate is recommended when the saw
blade engages in the material as well as when sawing plastic
and aluminium.

Orbital action switched off:

For working thin or hard material such as
sheet metal or steel.
For achieving clean cutting edges.

Orbital action switched on:

For working non-ferrous metals, hardwood,
plastics or materials of medium density.

For working soft materials, e.g., soft building
materials, insulation material, softwood, tree
wood.

1 609 92A 2WG | (9.11.16) Bosch Power Tools

OBJ_BUCH-1399-002.book Page 7 Wednesday, November 9, 2016 9:45 AM

After longer periods of work at low stroke rate, the machine
can heat up considerably. Allow the machine to cool down by
running it for approx. 3 minutes at maximum stroke rate.

Working Advice

Tips
 When sawing light building materials, observe the

statutory provisions and the recommendations of the
material suppliers.

Check wood, press boards, building materials, etc. for foreign
objects such as nails, screws or similar, and always use the
correct sawblade.

Switch the machine on and guide it toward the workpiece.
Position the footplate 2 onto the surface of the work and saw
through the material applying uniform contact pressure and
feed. After completing the working procedure, switch the
machine off.

If the saw blade should jam, switch the machine off immedi­ately. Widen the gap somewhat with a suitable tool and pull
out the machine.

Plunge Cutting (see figures D– E)
 The plunge cutting procedure is only suitable for treat-

ing soft materials such as wood, plaster board or simi­lar! Do not work metal materials with the plunge cut­ting procedure!

Use only short saw blades for plunge cutting.
Place the machine with the edge of the footplate 2 onto the

workpiece and switch on. For power tools with stroke speed
control, set the maximum stroke speed. Press the power tool
firmly against the workpiece and allow the saw blade to slowly
plunge into the workpiece.

As soon as the footplate 2 fully lays on the surface of the work­piece, continue sawing alongside the desired cutting line.

For certain work, the saw blade 1 can also be inserted turned
through by 180 ° and the sabre saw can be guided accordingly
in a reversed manner.

Flush Cuts (see figure F)

Using elastic bimetal saw blades, items still attached to a wall
(e. g. projecting building elements such as water pipes, etc.)
can be sawn off flush at the wall.

 Pay attention that the saw blade always extends be-

yond the diameter of the material being worked. There
is danger of kickback.

Position the saw blade directly against the wall and apply
some lateral pressure via the tool until the footplate faces
against the wall. Switch the power tool on and saw through
the workpiece, applying constant lateral pressure.

Coolant/Lubricant

When sawing metal, coolant/lubricant should be applied
alongside cutting line because of the material heating up.

Maintenance and Service

Maintenance and Cleaning

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

plug.

 For safe and proper working, always keep the machine

and ventilation slots clean.

Clean the saw blade holder preferably with compressed air or
a soft brush. Remove the saw blade from the power tool for
this. Ensure proper operation of the saw blade holder by ap­plying a suitable lubricant.

Heavy contamination of the machine can lead to malfunc­tions. Therefore, do not saw materials that produce a lot of
dust from below or overhead.

If the machine should fail despite the care taken in manufac­turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.

In all correspondence and spare parts order, please always in­clude the 10-digit article number given on the type plate of
the machine.
