GENERAL SAFETY RULES
GEA001-3
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 battery-operated (cordless) power
tool.
SAVE THESE INSTRUCTIONS.
Work area safety
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.
Personal 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 protec-
tion. Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal inju-
ries.
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 plug-
ging in power tools that have the switch on invites
accidents.
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 bal-
ance 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 chil-
dren 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.

7
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 con-
ditions and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
Service
23. 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.
24. Follow instruction for lubricating and changing
accessories.
25. Keep handles dry, clean and free from oil and
grease.
SPECIFIC SAFETY RULES
GEB016-1
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to jig saw safety rules. If you use this tool unsafely or
incorrectly, you can suffer serious personal injury.
1. Hold power tools by insulated gripping surfaces
when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Contact with a "live" wire will make exposed metal
parts of the tool "live" and shock the operator.
2. Use clamps or another practical way to secure
and support the workpiece to a stable platform.
Holding the work by hand or against your body
leaves it unstable and may lead to loss of control.
3. Always use safety glasses or goggles. Ordinary
eye or sun glasses are NOT safety glasses.
4. Avoid cutting nails. Inspect workpiece for any
nails and remove them before operation.
5. Do not cut oversize workpiece.
6. Check for the proper clearance beyond the work-
piece before cutting so that the blade will not
strike the floor, workbench, etc.
7. Hold the tool firmly.
8. Make sure the blade is not contacting the work-
piece before the switch is turned on.
9. Keep hands away from moving parts.
10. Do not leave the tool running. Operate the tool
only when hand-held.
11. Always switch off and wait for the blade to come
to a complete stop before removing the blade
from the workpiece.
12. Do not touch the blade or the workpiece immedi-
ately after operation; they may be extremely hot
and could burn your skin.
13. Do not operate the tool at no-load unnecessarily.
14. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.
15. Always use the correct dust mask/respirator for
the material and application you are working
with.
SAVE THESE INSTRUCTIONS.
WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.

Continuous running (Fig. 4)
For 4304 only
Press the trigger and at the same time move the lock
lever backward. To stop from this lock position, press the
trigger and release it.
Speed adjusting dial
(Fig. 4 for 4304 and Fig. 5 for 4305)
The tool speed can be adjusted between 500 and 3,000
strokes per minute by turning the adjusting dial. The dial
is marked 1 (lowest speed) to 6 (full speed). Refer to the
table below to select the proper speed for the workpiece
to be cut. However, the appropriate speed may differ
with the type or thickness of the workpiece. In general,
higher speeds will allow you to cut workpieces faster but
the service life of the blade will be reduced.
Cutting operation (Fig. 6)
Rest the base flat on the workpiece and gently move the
tool forward along the previously marked cutting line.
When cutting curves, advance the tool very slowly.
Bevel cutting (Fig. 7 & 8)
With the base tilted, you can make bevel cuts at any
angle between 0° and 45° (left or right). Loosen the bolt
on the bottom of the tool. Move the base so that the bolt
is positioned in the center of the cross-shaped slot in the
base. Tilt the base until the desired bevel angle is
obtained. The edge of the motor housing indicates the
bevel angle. (See Fig. 8) Then tighten the bolt to secure
the base.
Flush cutting (Fig. 9)
Loosen the bolt on the bottom of the tool and move the
base all the way back. Then tighten the bolt to secure the
blade.
Cutouts
Cutouts can be made with either of two methods A or B.
A) Boring a starting hole:
For internal cutouts without a lead-in cut from an
edge, pre-drill a starting hole more than 12 mm in
diameter. Insert the blade into this hole to start
your cut. (Fig. 10)
B) Plunge cutting:
Your need not bore a starting hole or make a
lead-in cut if you carefully do as follows:
1. Tilt the tool up on the front edge of the base, with the
blade point positioned just above the workpiece sur-
face. (Fig. 11)
2. Apply pressure to the tool so that the front edge of
the base will not move when you switch on the tool
and gently lower the back end of the tool slowly.
3. As the blade pierces the workpiece, slowly lower the
base of the tool down onto the workpiece surface.
4. Complete the cut in the normal manner.
Finishing edges (Fig. 12)
To trim edges or make dimensional adjustments, run the
blade lightly along the cut edges.
Metal cutting
Always use a suitable coolant (cutting oil) when cutting
metal. Failure to do so will cause significant blade wear.
The underside of the workpiece can be greased instead
of using a coolant.
Plastic base plate (Fig. 13)
Use the plastic base plate when cutting decorative
veneers, plastics, etc. It protects sensitive surfaces from
damage. To replace the base plate, remove the four
screws.
Anti-splintering devise (Fig. 14)
For splinter-free cuts, the anti-splintering device can be
used. Fit it into the base from below.
Guide rule (optional accessory) (Fig. 15)
When cutting widths of under 150 mm repeatedly, use of
the guide rule (rip fence) will assure fast, clean, straight
cuts. To install it, loosen the bolt on the front of the base.
Slip in the guide rule and secure the bolt.
Circular guide (optional accessory) (Fig. 16)
Use of the circular guide insures clean, smooth cutting of
circles (radius; under 200 mm. Insert the pin through the
center hole and secure it with the threaded knob. Move
the base of the tool forward fully. Then install the circular
guide on the base in the same manner as the guide rule
(rip fence).
Dust extraction (Fig. 17, 18 & 19)
The vacuum head is recommended to perform clean cut-
ting operations. Install the plastic cover on the tool by fit-
ting it into the notches in the tool.
To attach the vacuum head on the tool, insert the hook of
the vacuum head into the hole in the base. The vacuum
head can be installed on either left or right side of the
base. Then connect a Makita vacuum cleaner to the vac-
uum head.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
