General Power Tool Safety Warnings

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

below may result in electric shock, fire and/or serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE

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

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 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 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 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, use an extension 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 Fault Circuit Interrupter (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

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 part of the power tool may result in personal injury.

Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

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.

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.

Do not let familiarity gained from frequent use of tools allow you 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, changing 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, clean and free 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 with 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 away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to

outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

Service

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.

Never service damaged battery packs.

Service of battery packs should only be performed by the manufacturer or authorized service providers.

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 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 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 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.

Disconnect battery pack from tool before making any assembly, adjustments 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 housing and damage tool as well as 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.

Safety Rules for Cordless Planers

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

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.

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 internal wires may be misplaced or pinched or safety guard return springs may 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 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 chemicallytreated 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.

Assembly

Use only Bosch PA1208 planer blades. Using other planer blades may

cause injuries.

Wear protective gloves when changing planer blades. Edges are

sharp and may cause injury.

The PA1208 planer blades have two cutting edges, and may be reversed when one of the cutting edges becomes dull or chipped.

Do not attempt to sharpen or use resharpened used blades of any kind. Use only blades designated for use with this model, because other blades will cause vibration, decrease perfomance and may not clamp securely in blade holder.

▼BLADE AND WRENCH STORAGE AREA

When the battery pack 5 has been removed from the tool, there is a blade wrench 17 that is conveniently located inside the handle, where it is always handy and unlikely to get lost or misplaced (Fig. 2).

A spare blade can be stored in the blade drawer 7 (Fig. 2)

▼REVERSING OR REPLACING BLADES

To reverse or replace the blade 16:

A.Loosen the clamping screws 20 with blade wrench 17.

B.If necessary, loosen the blade clamp 19 by giving it a light blow with a wooden wedge.

C.With the blade clamp 19 loosened, push the blade guard 8 down.

D.Use a piece of wood to slide the

blade 16 lengthwise out of the blade/cutter drum 18, taking care to keep your fingers away from the sharp edges of the blade (Fig. 3).

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

▼ BLADE ALIGNMENT

The blade should be centered relative to the front 13 and rear 9 shoes (Fig. 4). Rotate the blade drum 18 by hand to verify that the blade doesn’t touch to any other part of the tool.

Make sure the blade sits correctly in the holder groove of the cutter drum. Ensure that the blade aligned flush with the side edge of the rear shoe 9 (Fig. 4). You may then secure the blade clamp 19 by tightening the screws 20. Your planer is ready for use.

Assembly

Shavings Extraction

Do not reach into the shavings ejector with your hands. They could be injured by

rotating parts.

To ensure optimum extraction of shavings and dust, always work with external dust extraction or the shavings bag (both sold separately).

GHO12V-08 offers 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 you remove the diverter 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 attachment out of the exhaust channel 27 (Fig. 5).

-Insert the shavings 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 attachment out of the exhaust channel 27 (Fig. 6).

-Insert the vacuum adapter into the exhaust channel 27.

Fig. 6

23

Fig. 7

24

-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 cleaner (both sold separately).

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

When vacuuming dry dust that is especially detrimental to health or carcinogenic, use a special vacuum cleaner / dust extractor.

Operating Instructions

Disconnect battery pack from tool before making any assembly,

adjustments or changing accessories.

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

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.

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 THE TOOL “ON”: Depress the “Lock-OFF” button 3 on either side of the tool and squeeze the trigger switch 4.

TO TURN THE TOOL “OFF”: Simply release the trigger switch 4.

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

Battery Charge Condition Indicator

Your tool is equipped with charge condition indicator lights 10 (Fig. 1). The indicator lights show the charge condition of the battery for a few seconds after tool activation.

LED	Capacity

	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.

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

Operating Instructions

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, which retracts 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 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 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-

Operating Instructions

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

Planer Stand

The planer stand 26 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 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 bevel width, use the V-groove 14 or not. The dimension a when

using the V-groove varies between 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 planer. When planning to create a rabbet, the blade guard 8 (Fig. 3, page 9) will be automatically lifted as needed by the surface of the workpiece that is adjacent to the area be rabbeted (Fig. 13).

A guiding device such as a clamped low, straight board can be used to provide guidance to the planer when creating rabbets (not shown).

The planer can be used to “clean up” existing rabbets using the rabbet’s side edge as the guiding device (Fig. 13).
