Work Area
Keep your work area clean and well lit.
Cluttered benches and 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 by-standers, children, and visitors
away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
Double Insulated tools are equipped with a
polarized plug (one blade is wider than the
other.) This plug will fit in a polarized outlet
only one way. If the plug does not fit fully in
the outlet, reverse the plug. If it still does
not fit, contact a qualified electrician to
install a polarized outlet. Do not change
the plug in any way. Double Insulation
eliminates the need for the three wire
grounded power cord and grounded power
supply system. Before plugging in the tool, be
certain the outlet voltage supplied is within the
voltage marked on the nameplate. Do not use
“AC only” rated tools with a DC power supply.
Avoid body contact with grounded surfaces
such as pipes, radiators, ranges and
refrigerators. There is an increased risk of
electric shock if your body is grounded. If
operating the power tool in damp locations is
unavoidable, a Ground Fault Circuit Interrupter
must be used to supply the power to your
tool. Electrician’s rubber gloves and footwear
will further enhance your personal safety.
Don't 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
to carry the tools or pull the plug from an
outlet. Keep cord away from heat, oil, sharp
edges or moving parts. Replace damaged
cords immediately. Damaged cords increase
the risk of electric shock.
When operating a power tool outside, use
an outdoor extension cord marked "W-A"
or "W." These cords are rated for outdoor use
and reduce the risk of electric shock. Refer to
“Recommended sizes of Extension Cords” in
the Accessory section of this manual.
Personal Safety
Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use tool while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
Dress properly. Do not wear loose clothing
or jewelry. Contain long hair. Keep your
hair, clothing, and gloves away from
moving parts. Loose clothes, jewelry, or long
hair can be caught in moving parts. Keep
handles dry, clean and free from oil and
grease.
Avoid accidental starting. Be sure switch is
“OFF” before plugging in. Carrying tools with
your finger on the switch or plugging in tools
that have the switch “ON” invites accidents.
Remove adjusting keys or wrenches before
turning the tool “ON”. A wrench or a key that
is left attached to a rotating part of the tool
may result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. Proper footing and
balance enables better control of the tool in
unexpected situations.
Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must be
used for appropriate conditions.
Tool Use and Care
Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand or
against your body is unstable and may lead to
loss of control.
!
WARNING
Power Tool Safety Rules
-3-
Do not force tool. Use the correct tool for
your application. The correct tool will do the
job better and safer at the rate for which it is
designed.
Do not use tool if switch does not turn it
“ON” or “OFF”. Any tool that cannot be
controlled with the switch is dangerous and
must be repaired.
Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing the tool. Such
preventive safety measures reduce the risk of
starting the tool accidentally.
Store idle tools out of reach of children and
other untrained persons. Tools are
dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools
sharp and clean. Properly maintained tools,
with sharp cutting edges are less likely to bind
and are easier to control. Any alteration or
modification is a misuse and may result in a
dangerous condition.
Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tools
operation. If damaged, have the tool
serviced before using. Many accidents are
caused by poorly maintained tools. Develop a
periodic maintenance schedule for your tool.
Use only accessories that are
recommended by the manufacturer for
your model. Accessories that may be suitable
for one tool, may become hazardous when
used on another tool.
Service
Tool service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified
personnel could result in a risk of injury. For
example: internal wires may be misplaced or
pinched, safety guard return springs may be
improperly mounted.
When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk of
electric shock or injury. Certain cleaning
agents such as gasoline, carbon tetrachloride,
ammonia, etc. may damage plastic parts.
Safety Rules for Planers
Secure the material being planed. Never
hold it in your hand or across legs. Small
workpiece must be adequately secured so
that the rotating planer blades will not pick it
up during forward motion of the planer.
Unstable support can cause the blades to
bind causing loss of control and injury.
Make sure the spring operated automatic
retracting rabbet guard returns to blade
covering position instantly. The blades are
hidden from view and you may be cut if
blade is contacted.
Always start the plane before blade is in
contact with the workpiece and allow the
blade to come to full speed. Tool can
vibrate or chatter if blade speed is too slow
at beginning of cut and possibly kickback.
Check the workpiece for nails, if there are
nails, either remove or set them well
below intended finished surface. If the
planer blades strike objects like nails it may
cause the tool to kickback and serious
personal injury may result.
Never leave the trigger locked “ON”.
Unplug the planer before changing
accessories. Before plugging the tool in,
check that the trigger lock is "OFF".
Accidental start-ups may occur if planer is
plugged in while changing an accessory.
After changing blades, rotate the blade
drum to make sure blades are not hitting
any part of the blade head housing and
the blade locking screws are tight.
Spinning blades could strike tool housing
and damage tool as well as possible injury.
Always hold the tool firmly with both
hands for maximum control.
Never pull the plane backward over the
workpiece. Loss of control may occur.
Do not put fingers or any objects into the
chip ejector or clean out chips while tool
is running. Contact with blade drum will
cause injury.
Remove plug from power source if it
becomes necessary to remove chips. The
blades are hidden from view and you may be
cut if blade is contacted.
Never place the plane down until the
blade is completely at rest. Surface
contact with coasting blade drum may cause
the plane to walk out of control.
Never use dull or damaged blades. Sharp
blades must be handled with care.
Damaged blades can snap during use. Dull
blades require more force to push the tool,
possibly causing the blade to break.
Some dust created by
power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to
cause cancer, birth defects or other
reproductive harm. Some examples of
these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement
and other masonry products, and
• Arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies,
depending on how often you do this type of
work. To reduce your exposure to these
chemicals: work in a well ventilated area,
and work with approved safety equipment,
such as those dust masks that are specially
designed to filter out microscopic particles.

connector (Fig.3) to keep your work
environment cleaner. The chip bag or
vacuum connector may be attached to either
end of the exhaust port.
Moving the port selector lever to position 1
(towards front of tool) discharges chips to
the left, while position 2 (towards rear of tool)
discharges chips to the right. (Fig. 1)
Included is the VAC002 adapter that will
connect the hood to 1-1/4” and 1-1/2”
vacuum hoses. An adapter to connect the
hood to 2-1/2" hoses is also available
separately.
PLANER BLADES
• There are three types of blades that can
be used with the Bosch 1594 planer;
standard mini tungsten carbide blades,
Bosch Woodrazor micrograin mini
tungsten carbide blades (standard
equipment with the Bosch 1594 planer),
and large HSS blades.
• While the Bosch 1594 mini tungsten
carbide blades are sharper and more
durable than standard mini tungsten
carbide blades, the assembly and
adjustment of both of Woodrazor and
standard tungsten carbide blades are the
same. Henceforth, all references in this
manual to “mini TC blades” refer to both
Woodrazor blades and standard mini
tungsten carbide blades.
• To use large HSS blades with the 1594 it
is necessary to purchase optional
accessories.
Wear protective gloves
when changing planer
blades. Edges are sharp and may cause
injury.
REMOVING MINI TUNGSTEN
CARBIDE BLADES
Mini TC planer blades have two cutting
edges, and may be reversed when one of
the cutting edges becomes dull or chipped.
(Fig. 6)
Before any work on the machine itself, pull
the power plug.
Always changes both blades at the same
time. Otherwise, imbalance can cause
vibration and reduce the useful service life of
the tool. Use only blades designated for use
with this model, because other blades can
cause vibration, decrease performance and
may not clamp securely in blade holder. Do
not attempt to sharpen or use re-sharpened
any TC blades.
To remove the blades:
1. Rotate the blade drum until the clamping
jaw is parallel to the planer shoe.
2. Loosen the three clamp screws by about
one revolution each. (It is not necessary to
remove the clamping jaw.) (Fig.4)
3. Slightly rotate the blade drum and use a
piece of wood to push the blade sideways
and out from under the clamping jaw.
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.

INSTALLING AND ADJUSTING MINI
CARBIDE BLADES
If the blades and/or holder are gummed and
difficult to remove, remove the clamping
jaws and screws and clean all surfaces with
mineral spirits; lacquer thinner or alcohol, as
this will ensure an accurate blade setting
and proper tool performance. (See
REMOVAL OF MINI TC BLADE HOLDERS
AND RETAINERS)
To install, carefully slide the blades onto
ridges on the blade holders.
To ensure proper operation and an even cut,
the blades must be positioned so that they
are:
• Centered relative to the front and rear
shoes.
• Aligned with each other.
• Positioned so that they will not touch
against any part of the planer when
rotated.
• 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.
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.)
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.
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.

clean the blade and clamp with mineral
spirits, lacquer thinner or alcohol.
4. Rotate the blade drum 180° and repeat
the procedure to remove the second
blade.
INSTALLATION OF HSS BLADES
AND RETAINERS
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.
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.)
To ensure proper operation and an even cut,
the blades must be positioned so that they
are:
• Centered relative to the front and rear
shoes.
• Aligned with each other.
• 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)
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)
4. Rotate the blade drum 180° and repeat
the procedure for the second blade
clamp.
REMOVING LARGE HSS BLADES
To remove the blades:
1. Rotate the blade drum until the clamping
jaw is parallel to the planer shoe.
2. Loosen and remove the three clamp
screws with the Torx key.
3. Also remove the clamping jaw.
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.
Rotate the blade drum 180° and repeat the
procedure to remove the second blade.

RESHARPENING HSS BLADES
Worn or dull HSS plane blades can be resharpened. The optimal blade angle of 50º
should be maintained when sharpening.
Once a total of 6 mm of steel has been
removed from tips of the blades, both blades
must be replaced because the minimum
HSS blade height is 23 mm from back to tip.
LEVELING OF HSS BLADES
A PA1206 HSS Blade Leveling Fixture
(optional accessory) is required to level new
or resharpened HSS blades. (Not necessary
with the PA1204 HSS Blades and Retainers,
which are leveled at the factory.)
1. Place the blade and blade retainer on the
leveling fixture and make sure that the
blade retainer engages in the grooves
intended for this purpose. (Fig. 9)
2. Press the plane blade against the stop in
front of the cutting edge to achieve the
proper depth and evenness (levelness)
and with the blade retainer in this position
and tighten it with the locking screws. This
will automatically adjust the blade to the
correct height and levelness.
3. Tighten the retainer screws.
4. Remove blade and retainer assembly from
the leveling fixture.

Operating Instructions
TRIGGER "ON/OFF" SWITCH
Hold the tool with both
hands while starting the
tool, since torque from the motor can
cause the tool to twist.
To turn tool "ON": depress the “Lock-Off”
release button from either side and squeeze
the trigger switch.
To turn the tool "OFF": release the trigger
switch and it will return to "OFF" position
automatically.
To increase switch life, do not turn switch on
and off while tool and drum are held against
a workpiece.
PLANING ACTION
Proper planing action helps to achieve the
desired result. With practice and experience,
it will become second nature. Make sure that
the workpiece is held in place securely on
your work surface, and standing
comfortably, hold the planer firmly with both
hands.
1. With the planer fully adjusted, place the
front shoe on the workpiece, (be certain
that the blade drum is not in contact with
the work) and start the planer as
described earlier.
2. With pressure on the front shoe, and the
fence against the side of the work (to
control the width or angle,) feed the planer
steadily until the full length of the rear
shoe passes over the edge of the
workpiece. (Fig. 10)
3. Then gradually transfer pressure to the
rear shoe, and continue planing to the end
of the cut.
4. Feed the planer at a uniform and
reasonable rate that does not put
excessive strain on the motor or blades,
(do not pull the planer back over the
surface already cut.)
5. Use progressive cuts until you are near
the desired depth, and then re-adjust to a
shallow cut for the final pass to obtain a
good surface finish.
The motor may stall if
improperly used or
overloaded. Reduce the pressure (feed
rate) or depth of cut to prevent possible
damage to the tool if the motor labors.
!
CAUTION
!
WARNING
DEPTH OF CUT & FEED RATE
The cutting depth (planing depth) is
determined by the difference in height
between the adjustable front shoe and the
fixed rear shoe of the planer. The depth
knob adjusts the front shoe, which retracts
and exposes the blade and determines the
amount of material removed from the
workpiece. The cutting depth range is from 0
to 3/32” or 2.6 mm per pass. (Fig. 1)
The appropriate depth of cut and feed rate
depends on the workpiece material:
To avoid clogging and/or damage to the
motor, a more shallow (thin) cut and/or a
slower feed rate may be needed if the
material has any of these characteristics:
hardness; gumminess, sappiness, moisture,
paint, varnish and/or knots. Also, when
planing against the grain or across the grain
rather than with the grain, a shallower cut
and/or slower feed rate is required.
Whenever possible, test by planing a similar
piece of scrap material.
Use multiple, progressive cuts to achieve the
total desired depth.
Start with a shallow cut. If the plane moves
freely through the workpiece with no
excessive load on the motor, the depth
setting can be increased before the next cut.
(Do not change depth of cut while planing.)
When near the desired total depth, re-adjust
the planing depth to a shallow setting for the
final cut to obtain a good surface finish.
Adjusting the Depth of Cut: Rotate depth
adjustment knob clockwise until the
indicator is aligned with the desired cutting
depth on the depth scale (Fig. 1).
FIG. 10
PARK
REST
SHOE
PARK REST STAND
The park rest stand automatically springs
down to help keep the blade from coming in
contact with the work surface when planer is
not in use (Fig. 11). The park rest stand is
designed to swing up and out of the way by
it itself when the back of the plane crosses
the leading edge of the workpiece (Fig. 10).
It will also swing up when planing begins in
the middle of the work piece (in from the
edge of the work piece).
UNCLOGGING THE CHIP EXHAUST
SYSTEM
Remove plug from power
source if it becomes
necessary to manually remove chips. The
blades are hidden from view and you may be
cut if contacted.
To minimize the possibility of clogging, make
sure:
1. Chip eject lever is all the way forward (left
eject) or back (right eject).
2. The depth of cut is reasonable for the
material.
3. The feed rate is reasonable for the
material.
(See FEED RATE & DEPTH OF CUT)
If clogging occurs, stop the planer and move
the chip eject lever back and forth. If this
does not break up the clog, unplug the
planer and carefully insert a screwdriver or
similar object into the dust port to break up
the clog.
DELUXE BEVEL GUIDE FENCE
The Deluxe Bevel Guide Fence (Fig. 12) can
be used to cut various desired widths, with
the additional capability of guiding the planer
on any angle up to 45 degrees, to allow
edge chamfering (Fig. 13).
Installing the angle fence: Place the wing
knob through the appropriate hole in the
guide bracket and screw into the housing.
Securely tighten wing knob (Fig. 1).
Setting the cutting width: Loosen wing
knob and using the width scale, slide the
fence along the guide bracket to the desired
position. Securely tighten wing knob (Fig. 1).
Setting the cutting angle: Loosen round
knobs and pivot the fence to the desired
position. Securely tighten round knobs
(Fig. 1).
Note that the adjustable front shoe contains
three chamfer V-grooves, which will follow
the corner of a workpiece to allow easier
handling when using the deluxe angle/width
fence (Fig. 13).

the guide fence is likely to slip.
RABBETING DEPTH STOP
The optional rabbeting depth stop accessory
(Fig. 1) allows the user to set any rabbeting
depth from 0 to 5/16 inch. For best results, it
is important that the blade be properly
aligned (See "BLADE ALIGNMENT"). The
width of the rabbet is controlled by the width
fence. The final depth is achieved by
repetitive cutting until the rabbeting depth
guide contacts the workpiece. The maximum
rabbeting depth is 5/16"
Setting the rabbet depth: Loosen wing
knob and using the depth scale on the
rabbeting depth stop, set the desired rabbet
depth. Securely tighten wing knob.
DRIVE BELT
The drive belt is a normal maintenance part
and should be inspected periodically for
wear. If the drive belt shows signs of drying
out, cracking or tearing, it should be
replaced. If the drive belt will not track
properly or comes off the pulleys, it should
be replaced.
Installing new drive belt: Loosen screw and
remove the drive belt cover. Cut and remove
the worn drive belt. Before installing the new
drive belt, clean both pulleys thoroughly.
First place the new drive belt onto the drive
pulley then rotate clockwise while pushing
the belt onto the driven pulley. Reinstall the
drive belt cover and securely tighten screw
(Fig. 15).

Service
Preventive maintenance
performed by unauthorized
personnel may result in misplacing of
internal wires and components which
could cause serious hazard. We
recommend that all tool service be performed
by a Bosch Factory Service Center or Authorized Bosch Service Station.
TOOL LUBRICATION
Your Bosch tool has been properly lubricated
and is ready to use. It is recommended that
tools with gears be regreased with a special
gear lubricant at every brush change.
CARBON BRUSHES
The brushes and commutator in your tool
have been engineered for many hours of
dependable service. To maintain peak
efficiency of the motor, we recommend every
two to six months the brushes be examined.
Only genuine Bosch replacement brushes
specially designed for your tool should be
used.
BEARINGS
After about 300-400 hours of operation, or at
every second brush change, the bearings
should be replaced at Bosch Factory Service
Center or Authorized Bosch Service Station.
Bearings which become noisy (due to heavy
load or very abrasive material cutting) should
be replaced at once to avoid overheating or
motor failure.
Cleaning
To avoid accidents always
disconnect the tool from
the power supply before cleaning or
performing any maintenance. The tool may
be cleaned most effectively with compressed
dry air. Always wear safety goggles when
cleaning tools with compressed air.
Ventilation openings and switch levers must
be kept clean and free of foreign matter. Do
not attempt to clean by inserting pointed
objects through openings.
Certain cleaning agents
and solvents damage
plastic parts. Some of these are: gasoline,
carbon tetrachloride, chlorinated cleaning
solvents, ammonia and household detergents
that contain ammonia.
Clean the park rest shoe regularly and ensure
that it springs back freely.
