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

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.
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

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 energizing power tools that have the
switch on invites accidents.
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.
1594
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.
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 overreach. Keep proper footing and
balance at all times. This enables better
control of the power tool in unexpected
situations.
Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Dress properly. Do not wear loose clothing
or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose
clothes, jewelry or long hair can be caught in
moving parts.
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.
If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce dust-
related hazards.
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.

Power tool use and care
If operating a power tool in a damp location
is unavoidable, use a Ground Fault Circuit
Interrupter (GFCI) protected supply. Use of
an GFCI reduces the risk of electric shock.
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.

• Aligned with each other.
3. Slightly rotate the blade drum and use a
piece of wood to push the blade, holder and

keep your fingers away from the sharp
edges of the blade. If the blade is gummed
and difficult to remove, you may clean the
blade and clamp with mineral spirits, lacquer
thinner or alcohol.
• Positioned so that they will not touch against
any part of the planer when rotated.
FIG. 5
• Evenly pressed back toward the holder to
ensure that they are level.
INSTALLATION PROCEDURE
1. Align the groove on top of the blade with the
ridge of the blade holder and carefully slide
the blade onto the blade holder, as shown in
Figure 6.
4. Rotate the blade drum 180° and repeat the
procedure to remove the second blade.
INSTALLATION OF HSS BLADES
AND RETAINERS
2. Using a block of wood push the TC blade
back towards the blade holder so that the
inner side of the blade is pressed against
the sloping part of the blade holder. (This will
ensure that the blades are level.)
Before inserting a new or sharpened blade,
clean all surfaces (blades, retainer and drum)
with mineral spirits; lacquer thinner or alcohol,
as this will ensure an accurate blade setting
and proper tool performance.
2. Place a properly-oriented clamping jaw over
the blade. (Fig. 4)
3. Tighten the three clamp screws with the
Torx key using the correct tightening
sequence (1,2,3). (Fig. 4)
3. Then tighten the Torx clamping screws
using the correct tightening sequence
(1,2,3), as shown in Figure 4, and your
planer is ready for use.
New or re-sharpened plane blades must be
properly leveled before installation using the
optional PA1206 HSS Blade Leveling Fixture.
(The PA1204 HSS Blades with Retainers are
leveled at the factory.)
4. Rotate the blade drum 180° and repeat the
procedure for the second blade clamp.
FIG. 6
REMOVING LARGE HSS BLADES
To remove the blades:
1. Rotate the blade drum until the clamping jaw
is parallel to the planer shoe.
Blade Retainer Screws - Under normal
circumstances, the position of the retainer on
the mini TC blade holders does not require
readjustment. If fact, the screws that attach the
retainer to the blade holder are factory sealed
with a yellow fastening compound that should
not be disturbed. However, if you believe that
adjustments must be made, proper adjustment
is critical, and it is best performed by a Bosch
Factory Service or Bosch Authorized Service
Center.
BLADE
HOLDER
To ensure proper operation and an even cut,
the blades must be positioned so that they are:
2. Loosen and remove the three clamp screws
with the Torx key.
• Centered relative to the front and rear
shoes.
3. Also remove the clamping jaw.
• Aligned with each other.
4. Slightly rotate the blade drum and use a
piece of wood to push the blade and retainer
sideways and out of the blade drum. Make
sure to keep your fingers away from the
sharp edges of the blade. If the blade is
gummed and difficult to remove, you may
clean the blade and clamp with mineral
spirits, lacquer thinner or alcohol.
• Positioned so that they will not touch against
any part of the planer when rotated.
Procedure:
1. To install the blades, carefully slide the
blade/retainer assembly sideways to over
one of the two clamping areas on the blade
drum. The retainer must engage in the
groove. (Fig. 8)
Rotate the blade drum 180° and repeat the
procedure to remove the second blade.
