 Work area safety

Ke ep 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 su rfaces, 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 or moving parts. Damaged

or entangled cords increase the risk of electric shock.

When operating a power tool outdoors, us e 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 unavoidable, use a Ground Fa ult Circuit In terrupte r ( GFCI) protected supply. Use of an GFCI 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

Read all safety warnings, instructions, illustrations and speciﬁcations provided with this power tool. Failure to follow all instructions listed

General Power Tool Safety Warnings

of drugs, alcohol or medication. A moment of inattention while operating 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.

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.

Remove any adjusting key or wrench before turning the power tool on. A

wrench or a key left attached to a rotating pa rt o f the power tool may result in personal injury.

Do not overreach. Keep proper footing and balance at all times. This enables

be t ter control of the po wer tool in unexpected situations.

Dr ess proper ly. Do not we ar 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.

If devic es ar e prov ided for the co nnection of dust extractio n and collection facilities, ensure these are connected and properly used. Use of dust

co l lection can red uce dust-re lated hazards.

Do not let familiar ity gain ed from fr equent use of tools allow yo u to become complacent and ignore tool safety principles. A careless action can

cause severe injury within a fraction of a second.

 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 remove the battery pack, if detachable, from the power tool before making any adjustments, chang ing 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 and accessories. Check for misalignment or binding 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 accordance 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.

Keep handles and grasping surfaces dry, cl ean and f ree from oil and grease.

Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

 Battery tool use and care

Recharge only wi t h the charger specified by the manufacturer. A charger

that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

Use power tools only with specifically designated battery packs. Use of any

other battery packs may create a risk of injury and fire.

When battery pack is not in use, keep it aw ay fro m othe r meta l obje cts li ke paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to

Safety Rules for Cordless Planers

Wait for the cutter to stop before setting the tool down. An exposed rotating cutter

may engage the surface leading to possible loss of control and serious injury.

Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the workpiece by

your hand or against the body leaves it unstable and may lead to loss of control.

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.

Always start the planer before blade is in contact with the workpiece and allow the bl ade to come to full s peed. Tool can

vibrate or chatter if blade speed is too slow at beginning of cut and possibly kickback.

Check the blade guard for proper closing before each use. Do not operate tool if the blade guard does not move freely and close instantly. Never clamp or tie the blade guard in the open position. Hands

contacting the blade can cause serious personal injury.

Keep hands away from the blade. Hands

contacting the blade can cause serious personal injury.

Check the workpiece for nails, if there are na ils, eithe r re move or s et t hem w ell 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.

Disconnect battery pack from tool before ma king any as sembl y, adjustment s or changing accessories. Such preventive

safety measures reduce the risk of starting the tool accidentally.

After changing blades, rotate the blade cylinder (cutter 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

hous i n g a n d d a m a g e t o o l a s w e l l a s possible injury.

Always hold the tool firmly with both hands. This provides maximum control for the operator.

Never pull the planer backward over the workpiece. Loss of control may occur.

Do not put fingers or any objects into the shavings exhaust channel or clean out shavings while tool is running. Contact

with blade drum will cause injury.

General Power Tool Safety Warnings

another. Shorting the battery terminals t

ogether may cause burns or a fire.

Under abusive conditions, liquid may be ejected from the battery, avoid contact. If contact accidentally occurs, flush with water. If l i q u i d contacts eyes, additionally seek medical help. Liquid

eject e d from the battery may cause irritation or burns.

Do not use a battery pack or tool that is damaged or modiﬁed. Damaged or modiﬁed

batt e r i e s may e x h ibit unpre d i c t a b l e behaviour resulting in ﬁre, explosion or risk of injury.

Do not expose a battery pack or tool to ﬁre or excessive temperature. Exposure

to ﬁre or temperature above 265 °F may cause explosion.

Follow all charging instructions and do not charge the battery pack or tool

outside the temperature range speciﬁed i

n the instructions. Charging improperly

or at temperatures outside the speciﬁed range may damage th e battery and increase the risk of ﬁre.

 Service

Have your power tool serviced by a qualified re pair p erson using only identical replacement parts. This will

ensure that the safety of the power tool is maintained.

Never service damaged battery packs.

Service of battery packs should only be pe r formed by the manufac turer or authorized service providers.

Additional Safety Warnings

Develop a periodic maintenance schedule for your tool. When cleaning a tool be careful not to disassemble any portion of the tool since inte r n a l wires may b e mi splaced or pinche d or safety guar d retu r n springs m a y be improperly mounted. Certain cleaning agents such as

gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.

Ensure the switch is in the off position before inserting battery pack. Inserting the

battery pack into power tools that have the switch on invites accidents.

Some dust created by

power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to caus e cancer, birth def e c t s 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 t hese exp osures v arie s, 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.

Disconnect battery pack from tool if it becomes necessary to remove shavings.

The blades are hidden from view and you may be cut if blade is contacted.

Never use dull or damaged blades. Sharp

blad e s must be handled with ca r e .

Damaged blades can snap during use. Dull blades require more force to push the tool, possibly causing the blade to break.

 Shavings Extraction

Do not reach into the

shavings ejector with

your hands. They could be injured by rotating parts.

To e n s u r e op t i mum ex traction of shavings and dust, always work with external dust extraction or the shavings bag (both sold separately).

GHO1 2 V - 0 8 of f ers several ways of dealing with wood shavings and dust (Fig. 5):

 SHAVINGS DIVERTER

Shavings diverter 13 lets you direct the flow of shavings and dust to one of the sides of the planer. To use it, simply insert the diverter 13 into the exhaust channel 27 on the side you prefer the shavings to come out.

If y o u remove the diver t e r 13, the shavings will be ejected on both sides of the planer.

Clean the shavings diverter 13 regularly. For that, switch off the power tool. Remove the shavings ejector and shake it out. Use a suitable tool (e.g. a piece of wood, etc.) to clean a clogged shavings diverter.

 SHAVINGS/DUST BAG

(Sold separately)

Shavings/dust bag 22 is suitable for small volume tasks. It can be attached to either side of the planer.

- Remove the diverter 13 or any other attach ment out of the exhaust channel 27 (Fig. 5).

- Insert the shav ings bag into the exhaust channel 27 (Fig. 5).

- Lock the latch 24 as shown in Fig. 7.

 VACUUM ADAPTER

(Sold separately)

Vacuum adapter 23 lets you connect the planer to a vacuum cleaner. The vacuum adapter can be attached to either side of the planer.

- Remove the diverter 13 or any other attach ment out of the exhaust channel 27 (Fig. 6).

- Insert the vacuum adapter into the exhaust channel 27.

- Lock the latch 24 as shown in Fig. 7.

- Insert the vacuum hose 21 into the vacuum adapter 23 (Fig. 5).

NOTE: Bosch VH-series hoses can be connected using the snap fasteners 25 on those hoses. Other Bosch hoses and some other tool manufacturers’ vacuum hoses will also connect directly to the adapter 23. For connection to 1¼" and 1½" hoses, use the Bosch VAC024 or VAC002 adapter (sold separately).

- Connect the vacuum hose 21 to a vacuum clean er (both sold separately).

The vacuum cleaner must be suitable for the material being worked.

When vac u u m i n g dr y du st that is especially detrimenta l t o h ealth or carcinogenic, use a special vacuum cleaner / dust extractor.

Disconnect battery

pack from tool befo r e maki n g any assembl y , adjustments or changing accessories.

Such preventive safety measures reduce the risk of starting the tool accidentally.

Chec k the blade

guar d f or proper clos i n g before e a c h use. Do not operate tool if the blade guard does not move freely and close instantly. Never clamp or tie the blade guard in the open position. Hands contacting the

blade can cause serious personal injury.

Keep hands away

from the blade.

Hands contacting the blade can cause serious personal injury.

 Trigger "ON/OFF" Switch

Hold the t o o l with

both hands while starting the tool, since torque from the motor can cause the tool to twist.

TO TURN THE TOOL “ON”: Depress the

“Lock-OFF” button 3 on either side of the tool and squeeze the trigger switch 4.

TO TU RN THE TOOL “OF F”: Sim ply release the trigger switch 4.

To increase switch life , d o not turn switch on and off while tool and drum are held against a workpiece.

 Battery Charge Condition

Indicator

Your tool is equipp e d with charge condition indicator lights 10 (Fig. 1). The indicator lights show the charge cond i t i o n of the battery for a few seconds after tool activation.

 Convenience Brake

When the trigger is released it activates the electrical brake to stop the blade quickly. This feature is especially useful when making repetitive cuts.

 Planing Action

Proper planing action helps to achieve the desired result. With practice and expe r i e n c e , it wi l l become s e c o n d 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.

A. With the planer fully adjusted, place

the front shoe 13 on the workpiece, (be certain that the blade 16 is not in contact with the work) and start the planer as described earlier.

B. With pressure on the front shoe 13

feed the planer steadily until the full length of the rear shoe 9 passes over the edge of the workpiece. (Fig. 8)

C. Then gradually transfer pressure to

the rear shoe 9, and continue planing to the end of the cut.

D. If pressure is not maintained over the

rear shoe 9 through the end of the cut, a divot may be created in the workpiece once the front shoe 13

clear the end of the workpiece 30. To minimize this possibility, use a 3-way edge clamp 32 (not included) to hold a piece of scrap wood 31 (at least 1-1/2" [38 mm] thick) on the end of the workpiece 30, aligned with the surface to be planed (Fig. 9). Doing this moves the location of a potential divot off the workpiece and on to the piece of scrap wood.

E. Feed the planer at a uniform and

reasonable rate that does not put excessive strain on the motor or blade, (do not pull the planer back over the surface already cut.)

F. Use progressive cuts until you are

near the desired depth, and then readjust to a thin 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.

 Depth of Cut and Feed Rate

The cutting depth (planing depth) is determined by the difference in height between the adjustable front shoe 13 and the fixed rear shoe 9 of the planer. The depth knob 1 adjusts the front shoe 13, w hich retrac ts and exposes the blade and determines the amount of material removed from the workpiece.

The appropriate depth of cut and feed rate depends on the workpiece material:

To avoid clogging and/or damage to the motor, a thinner cut and/or a slower feed rate may be needed if the material has any of th e s e charac t e r i s t ics: hard n e s s ; gummin e s s , sappin e s s , 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 r ate is r e q u i r ed. Whenever possible, test by planing a similar piece of scrap material.

Use multiple, progressive cuts to achieve the total desired depth.

Start with a thin cut. If the planer moves freely through the workpiece with no excessive load on the motor, the depth setting can be increased before the next cut.

When near the desired total depth, re-

adju s t the planing depth to a th i n setting for the final cut to obtain a good surface finish.

 ADJUSTING THE DEPTH OF CUT

- Turn depth adjustment knob 1 as shown in Fig. 10 to increase the depth of cut from 0 to .04 inches.

- To use the extended depth of cut range, press and hold the Max button 2 and keep turning the depth knob 1 to set the depth of cut between .04 and .08 inches.

suitable depth range based on the planing width and the material being worked on.

 Planer Stand

The pl a n e r stand 26 a utomatically springs down to help keep the blade from coming in contact with the work surface when planer is not in use (Fig.

11). The planer stand is designed to swing up and out of the way by itself when the back of the planer crosses the leading edge of the workpiece (Fig. 9). It will also swing up when planing begins in the middle of the work piece (in from the edge of the work piece).

 Beveling Edges

The V-groove 14 in the front shoe of the planer allows quick and easy beveling of workpiece edges (Fig. 12).

Depending on required bev e l widt h , use the V-groove 14 or not. The dime n s i o n a when usin g the V- g r oove vari e s be t ween 0.08

and 0.2 inches (2.1 and 5mm). The dimension a when using just the shoe 13 varies between 0 and 0.11 inches (0 and 2.8mm).

Place the planer with the V-groove onto the edge of the workpiece and guide it along the edge.

 Rabbeting

The GHO12V-08 can create rabbets up to 2.2"/ 56mm wide (a) and 0.67"/17mm deep (b). Keep in mind that it may take many passes to create rabbets using a plan e r . When planning to cr eate a rabbet, the blade guard 8 (Fig. 3, page
