WARNING! “READ ALL INSTRUC-

TIONS”. Failure to follow the SAFETY RULES
identified by the BULLET (•) symbols listed
BELOW and other safety precautions, may
result in serious personal injury. Keep these
operating instructions with this product.

GENERAL SAFETY RULES

for all Power Tools

Work Area

• KEEP WORK AREAS CLEAN. Cluttered
areas and benches invite accidents.

• AVOID DANGEROUS ENVIRONMENT.
Don’t use power tools in damp or wet locations.
Do not expose power tools to rain. Keep work
area well lit.

• AVOID GASEOUS AREAS. Do not oper­ate portable electric tools in explosive atmo­spheres in presence of flammable liquids or
gases. Motors in these tools normally spark,
and the sparks might ignite fumes.

• KEEP CHILDREN AWAY. Do not let
visitors contact tool or extension cord. All
visitors should be kept away from work areas.

Personal Safety

• GUARD AGAINST ELECTRIC SHOCK.
Prevent body contact with grounded surfaces
such as pipes, radiators, ranges and refrigerator
enclosures. Rubber gloves and non-skid foot­wear are recommended when working out­doors, where damp or wet ground may be
encountered. A Ground Fault Circuit Inter­rupter protected power line must be used for
these conditions.

• DRESS PROPERLY. Do not wear loose
clothing or jewelry. They can be caught in
moving parts. Wear protective hair covering to
contain long hair.

• USE SAFETY EQUIPMENT. WEAR
SAFETY GOGGLES or glasses with side
shields. Wear hearing protection during ex­tended use of power tools and dust mask for
dusty operations.

• STAY ALERT. USE COMMON SENSE.
Watch what you are doing. Do not operate tool
when you are tired or under influence of drugs.

•

REMOVE ADJUSTING KEYS AND
WRENCHES.
keys and adjusting wrenches are removed from
tool before turning it on.

• AVOID ACCIDENTAL STARTING. Don’t

Form habit of checking to see that

carry plugged in tool with finger on switch. Be
sure the switch is OFF before being plugged in.

• DON’T OVERREACH. Keep proper foot­ing and balance at all times.

• BEFORE CONNECTING THE TOOL to a
power supply (receptacle, outlet, etc.) be sure
the voltage supplied is the same as that speci­fied on the tool’s nameplate. A power supply
with voltage greater than that specified for the
tool can result in serious injury to the user - as
well as damage to the tool. If in doubt, DO NOT
PLUG IN THE TOOL. Using a power supply
with voltage less than the nameplate rating is
harmful to the motor.
“Volts AC” designated tools are for Alternating
Current 50-60 Hz only. “Volts DC” designated
tools are for Direct Current. Do not use AC
designated tools with DC power supply. Do not
use electronic speed controlled tools with DC
power supply.

Tool Use and Care

• DON’T FORCE TOOL. It will do the job
better and safer at the rate for which it was
designed.

• USE RIGHT TOOL. Don’t force small tool
or attachment to do the job of a heavy-duty tool.
Don’t use tool for purpose not intended - for
example; don’t use a circular saw for cutting
tree limbs or logs.

• SECURE WORK. Use clamps or a vise to
hold work. It’s safer than using your hand and
it frees both hands to operate the tool.

• DON’T ABUSE CORD. Never carry tool by
cord or yank it to disconnect from receptacle.
Keep cord from heat, oil, and sharp edges.
Always keep cord away from the spinning
blade, bits or any other moving part while the
tool is in use.

• OUTDOOR USE EXTENSION CORDS.
When tool is used outdoors, use only extension
cords suitable for use outdoors and marked with
suffix W-A (for UL), or W (for CSA). Refer to
section “Extension Cords”, for proper cord use.

• DISCONNECT TOOLS. When not in use,
before servicing, or when changing blades,
bits, cutters, etc.

• STORE IDLE TOOLS. When not in use,
tools should be stored in dry, high or locked up
place - out of the reach of children.

• DO NOT ALTER OR MISUSE TOOL.
These tools are precision built. Any alterations
or modifications not specified is misuse and

BM 2609931094 6/95 12/14/98, 4:19 PM5

may result in a dangerous condition.

• THE USE OF ANY ACCESSORIES not
specified in this manual may create a hazard.

• MAINTAIN TOOLS WITH CARE. Keep
tools sharp and clean for better and safer perfor­mance. Follow instructions for lubricating and
changing accessories. Inspect tool cords peri­odically and if damaged, have repaired by au­thorized service facility. Inspect extension
cords periodically and replace if damaged. Keep
handles dry, clean and free from oil and grease.

• CHECK DAMAGED PARTS. Before fur­ther use of the tool, a guard or other part that is
damaged should be carefully checked to deter­mine that it will operate properly and perform
its intended function. Check for alignment of
moving parts, binding of moving parts, break­age of parts, mounting, and any other condi­tions that may affect its operation. A guard or
other part that is damaged should be promptly
and properly repaired or replaced. Have defec­tive switches replaced. Do not use tool if switch
does not turn it on or off.

• ALL REPAIRS, ELECTRICAL OR ME­CHANICAL, should be attempted only by
trained repairmen. Contact the nearest Bosch
Factory Service Center, or Bosch Authorized
Service Center or other competent repair cen­ter. Use only Bosch replacement parts, any
other may create a hazard.

Safety Rules for Planers

• Always start the plane before contacting the
workpiece and never pull the plane backwards
on the workpiece.

• Unplug the power cord before making ad­justments or changing/reversing blade sets.

• Make sure the spring operated automatic
retracting rabbet guard returns to blade cover­ing position instantly.

• Do not put fingers or any objects into the chip
ejector or clean out chips while tool is running.
Remove plug from power source if it becomes
necessary to remove chips.

• Before planing, check the workpiece for nails.
If there are nails, either remove or set them well
below intended finished surface.

• Small workpiece must be adequately secured
so that the rotating planer knives will not pick it
up during forward motion of the planer.

• After changing blades, rotate the cutter drum
to make sure blades are not hitting any part of
the blade head housing and the blade locking
screws are tight.

• Wear protective gloves and safety goggles.

• Always hold the tool firmly with both hands.

• Never place the plane down until the blade is
completely at rest.

Double Insulated Tools

• Double Insulation is a design concept
used in electric power tools which eliminates
the need for the three wire grounded power cord
and grounded power supply system. It is a
recognized and approved system by
Underwriter’s Laboratories, CSA and Federal
OSHA authorities.

IMPORTANT: Servicing of a tool with

double insulation requires care and knowledge
of the system and should be performed only by
a qualified service technician. WHEN SER­VICE IS REQUIRED USE ONLY IDENTI­CAL REPLACEMENT PARTS.

POLARIZED PLUGS: If your tool is 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 the
proper outlet. To reduce the risk of electric
shock do not change the plug in any way.

Extension Cords

• Replace damaged cords immediately. Use of
damaged cords can shock, burn or electrocute.

• If an extension cord is necessary, a cord with
adequate size conductors should be used to
prevent excessive voltage drop, loss of power
or overheating. The table below shows the
correct size to use, depending on cord length
and amperage rating on the tool’s nameplate. If
in doubt, use the next heavier gauge. Always
use U.L. and CSA listed extension cords.

"SAVE THESE INSTRUCTIONS"

overreach your work surface, or use the planer
in an uncomfortable position. This will extend
the life of your tool, and decrease the risk of
accidents. Remember, safety and good results
depend on sharp, properly adjusted cutting
blades. Keep your planer blades clean and
sharp, and replace or reverse dull blades when
your planer no longer performs smooth, fast
cuts.

Planer Blades

CAUTION! The planer blades are sharp and

fragile and must be handled carefully to avoid
injury to the user or damage to the blades .

Operating the Tool

Trigger "ON/OFF" Switch

WARNING! 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"
button and squeeze the trigger switch 7. To turn
the tool "OFF", release the trigger switch which
is spring loaded and will return to "OFF" posi­tion automatically.

To increase switch life, do not turn switch on
and off while tool is under the load.

Planing Action

Check that the workpiece is held in place se­curely on your work surface, and standing
comfortably, hold the planer firmly with both
hands. With the planer fully adjusted, place the
front shoe 10 on the workpiece, (be certain that
the cutter drum 23 is not in contact with the
work) and start the planer as described earlier.
With pressure on the front shoe 10, and the
fence against the side of the work (to control the
width or angle,) feed the planer steadily until
the rear shoe 22 fully engages the workpiece.
Now gradually transfer pressure to the rear
shoe, and continue planing to the end of the cut.
Feed the planer at a uniform and reasonable
rate, which does not put excessive strain on the
motor or blades, (do not pull the planer back
over the surface already cut.) Use progressive
cuts until you are near the desired depth, and
then readjust to a light cut for the final pass to
obtain a good surface finish.
Use a smooth, even planing action, and do not

The standard planer blades 24 have two cutting
edges, and may be reversed when one of the
cutting edges becomes dull or chipped. When
reversing or replacing blades, it is generally not
necessary to readjust the blade holders 26. If it
becomes necessary to adjust blade holder, take
planer to a Bosch Factory Service Center. To
avoid imbalance of the cutter drum 23, which
could result in vibration, premature tool wear
and poor work quality, always reverse or
replace blades as a set. Do not attempt to
sharpen used blades.

Reversing or Replacing Blades

To reverse or replace the blades loosen the
clamping screws 21 with blade wrench 9. With
the screws
loosened,

for this pur­pose. If the

26 24

blade is
gummed and
difficult to re­move, you
may clean the
blade with
mineral spir­its, lacquer
thinner or al­cohol. Clean all seating surfaces before rein­stalling the new blades, as this will ensure an
accurate blade setting and proper tool perfor­mance.

Blade Adjustment

Reassembly of the blades and blade holders is
essentially the reverse of the disassembly pro­cedure, but the following points should be
noted. When reinstalling the blades and blade
holders, it is important that the blade holders
rest firmly against the side stop of the cutter
drum 23 (position 1), before it is secured into
place. To ensure an even cut, it is important that
the blades are adjusted so that they align with
the outside edge of the front and rear shoes.
This alignment can be done as follows: place a
straight edge or a piece of wood along the
outside surface of the front shoe 10 and rear
shoe 22, then slide the planer blade 24 to just
contact the straight edge or wood (position 2).
Note that this adjustment must be done by
sliding the blade in its blade holder, and that the
blade holder

stop. You
may then
tighten the
clamping
screws 21
which secure
the blade holders evenly and alternately for
both blades, and your planer is ready for use.

Blade Leveling

The blade leveling screws 27 are factory set
with a fastening compound, and do not require
readjustment or removal under normal circum-

stances. If adjustment is required, it may be
done as follows. First set the front shoe 10 to
the zero "0" position. Next place a straight edge
over the front shoe 10 and rear shoe 22 and
check the height of both ends of the blades.
Both ends of the blades should just contact the
straight edge. If the blade edge is not perfectly
parallel with the shoes, you may raise or lower
the blade holder 26. With the clamping screws
21 loosened raise or lower the blade leveling
screws 27,
which will al-

21

low you to ad­just the blade
holder 26 up or
down until the
blade is paral­lel to the front
and rear shoes.
When this ad­justment is
complete, the clamping screws 21 must be
tightened firmly. Be certain that there is no
foreign material between the blades 24, the
blade holders 26 or the cutter drum 23.

These adjustments are critical, and are best
performed by a Bosch Factory Service or Bosch
Authorized Service Center if required, as the
blade leveling screws 27 must again be fas­tened with the proper chemical fastening com­pound.

Special Cutting Applications

The planer comes with two carbide reversible
blades. Optional blade sets**, which are listed
on page 3 of this instruction manual, may be
purchased for different applications.

CAUTION! When changing to an optional
blade set you must first purchase and install the
correct blade conversion kit, as listed. The
conversion kits include a different set of blade
holders and one set of optional blades. Once
the conversion kit is installed you may order
replacement blade sets separately. Each time
you change from one style blade set to the next,
you must always change the blade holders also.
The various blade holders and blade sets are not
interchangeable with each other.

knob 15. Be certain that the flat washer (sup­plied) is fitted between the bottom of the guide
fence and wing knob 15 or the guide fence is
likely to slip.

Tool Rest

The tool rest 31 swings down to help keep the
blade from coming in contact with the work
surface when plane is not in use.

Adjusting Depth of Cut

Proper cutting depth should be determined ac­cording to the hardness, gumminess or mois­ture content of the material being cut, as well as
the feed rate, and is largely a matter of experi­ence. Start with a light cut and increase the
depth setting if the plane moves freely through
the workpiece with no excessive load on the
motor. Do not change depth of cut while
planing.

The cutting depth is determined by the differ­ence in height between the adjustable front
shoe 10, and the fixed rear shoe 22 of the planer.
As the front shoe is adjusted, it retracts and
exposes the blades 24, which can then remove
the desired amount from the workpiece. The
cutting depth is graduated
from 0 to 2.5mm, and the "0"
indicates the blades are fully
retracted. The planer should
never be set down until the
blades have come to a com­plete stop.

Adjusting depth of cut: Rotate depth adjust­ment knob 3 until the indicator engages the
detent which indicates the desired cutting depth
on the depth scale 5. Each graduation mark is
equal to .1mm (.004"). The planer may be set
to cut any depth from 0 - 2.5mm (0 - 3/32").

Width Guide Fence

The width guide fence (not illustrated) can be
used to cut various desired widths.

Installing the guide fence: Place the wing knob
14 through the hole in the guide bracket 13 and
screw into the housing. Securely tighten wing
knob 14.

Setting the cutting width: Loosen wing knob 15
and slide the fence along the guide bracket 13 to
the desired position. Securely tighten wing

Deluxe Angle/Width Fence

The optional deluxe angle/width fence 17 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.

Installing the angle/width fence: Place the
wing knob 14 through the hole in the guide
bracket 13 and screw into the housing. Se­curely tighten wing knob 14.

Setting the cutting width: Loosen wing knob

15 and using the width scale 16, slide the fence
17 along the guide bracket 13 to the desired

position. Securely tighten wing knob 15.
Setting the cutting angle: Loosen round knobs

12 and pivot the fence 11 to the desired posi-
tion. Securely tighten round knobs 12.
Note that the adjustable front shoe 10 contains
a chamfer V-groove 20, which will follow the
corner of a workpiece to allow easier handling
when using the deluxe angle/width fence.

Rabbeting Depth Guide

The rabbeting depth guide 2 allows the user to
set any rabbeting depth from 0 to 15/16 inch (0
to 24mm). For best results, it is important that
the blades be properly aligned (See "blade

24mm

adjustment"). The width of the rabbet is con­trolled by the width fence. The maximum
cutting width is 3-1/4" (82mm), and the final
depth is achieved by repetitive cutting until the
rabbeting depth guide contacts the workpiece.
Setting the rabbet depth: Loosen wing knob 1
and using the depth scale on the rabbeting depth
guide 2, set the desired rabbet depth. Securely
tighten wing knob 1.

Chip Extraction

The planer comes with a chip exhaust port 4,
which may be used with a chip bag or a shop
vacuum and vacuum connector to keep your
work environ­ment cleaner.
The chip bag or
hose may be at­tached to either
end of the ex­haust port.
Moving the port
selector lever 6
to position 1
(towards front of tool) discharges chips to the
right, while position 2 (towards rear of tool)
discharges chips to the left.

Drive Belt

The drive belt 29 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
18 and remove
the drive belt
cover 19. Cut
and remove
the worn drive
belt 29. Be­fore installing
the new drive
belt, clean both pulleys thoroughly. First place
the new drive belt onto the drive pulley 30 then

Maintenance and Service

WARNING! Preventive maintenance per-

formed 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 at a
Bosch Factory Service Center.

Tool Lubrication

Your Bosch tool has been properly lubricated
and is ready for use. We recommend, that tools
with gears be regreased with a special gear
lubricant every time the brushes are changed.

Carbon Brushes

The brushes and commutator in your Bosch
tool have been engineered for many hours of
dependable service. To maintain peak effi­ciency of the motor, we recommend that 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 a Bosch Factory Service Center.
Bearings which become noisy (due to heavy
load or very abrasive material cutting) should
be replaced at once to avoid overheating and
motor failure.

Cleaning

WARNING! 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 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.

CAUTION! 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.
