BOSCH GFS 350 E Power Tenon Saw

General Power Tool Safety Warnings

• Read all safety warnings and all instructions. Failure to follow the warnings and instructions 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 the 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 that may ignite 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 and 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 residual current device (RCD) protected supply. Use of an RCD 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 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 a 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. The use of dust collection can reduce dust-related hazards.

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 the battery pack 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. 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.

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.

Machine-specific Safety Warnings

• Keep hands away from the sawing range. Do not reach under the workpiece. Contact with the saw blade can lead to injuries.
• Apply the machine to the workpiece only when switched on. Otherwise, there is the danger of kickback when the cutting tool jams in the workpiece.
• When the cut is completed, switch off the machine and then pull the saw blade out of the cut only after it has come to a standstill. In this manner, you can avoid kickback and can place the machine securely.
• Clamp material well. Do not support the workpiece with your hand or foot. Do not touch objects or the floor with the saw running. The danger of kickback.
• Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to an explosion. Penetrating a water line causes property damage or may cause an electric shock.
• Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more securely than by hand.
• Do not work materials containing asbestos. Asbestos is considered carcinogenic.
• Take protective measures when dust can develop during working that is harmful to one’s health, combustible or explosive. Example: Some dust are regarded as carcinogenic. Wear a dust mask and work with dust/chip extraction when connectable.
• Never use the machine with a damaged cable.
• Do not touch the damaged cable and pull the mains plug when the cable is damaged while working. Damaged cables increase the risk of an electric shock.
• The top and bottom of the cutting path must be free of obstructions.
• Switch the machine off immediately if the saw blade should become jammed.
• Wear protective gloves when changing cutting tools. Cutting tools become hot after prolonged usage.
• When using a cross-cutting table, strictly observe the respective safety warnings and working instructions!

Assembly

Replacing/Inserting the Saw Blade

• Before any work on the machine itself, pull the mains plug.
• Wear protective gloves when changing cutting tools. Cutting tools become hot after prolonged usage
• For all work on the power tool, attach the saw blade guard 8 to the saw blade.

Selecting a Saw Blade

With the saw blade guide offset, the fine cutting saw blade is suitable for cuts greater than the width of the saw blade. It is also intended to be used together with the cross-cutting table. The flush cutting saw blade allows for cuts flush to a backing. Cuts can only be carried out as deep as the saw blade is wide.

Inserting the Saw Blade

If required, both the flush cutting as well as the fine cutting saw blade can be inserted into the power tool in two positions turned by 180°. Before inserting, turn the saw blade to the required direction of cut (see the figures on the fold- out page). Insert hook 13 on the saw blade into hook 9 of the saw blade holder. Pivot the saw blade 7 toward the saw blade holder 10. Push the saw blade against the holder so that the cam 12 on the saw blade latches into the groove 11 on the SDS lever. Push the saw blade 7 back and forth in the saw blade guide 1 until the saw blade driving pin 2 can clearly be heard to engage in the saw blade. After engaging, the saw blade can no longer be moved in the saw blade guide 1.

Check the tight seating of the saw blade

• loose saw blade can fall out and lead to injuries.
• Only remove the saw blade guard 8 for sawing.

Removint the Saw Blade

• Attach the saw blade guard 8 onto the saw blade 7. Push the SDS clamping lever 6 of the saw blade release. The saw blade latching cam 12 pops out of the groove 11 of the lever. Remove the saw blade to the rear.

Operation

Starting Operation

• Observe the correct mains voltage! The voltage of the power source must agree with the voltage specified on the nameplate of the machine. Power tools marked with 230 V can also be operated with 220 V.

Switching On and Off

• To start the machine, push the On/Off switch 4 forwards.
• To lock the On/Off switch 4, additionally, push down the front of the switch.
• To switch off the machine, release the On/Off switch 4. When the On/Off switch is locked, press on the rear of the switch and then release it.

Controlling/Presetting the Stroke Rate

• With the thumbwheel for stroke rate preselection 5, the stroke rate can be preset and changed during operation.

• The required stroke rate is dependent on the material and the working conditions and can be determined by a practical trial.
• Reduce the stroke rate when positioning the saw blade onto the workpiece.

Operating Instructions

• Before any work on the machine itself, pull the mains plug.
• While sawing, always position the fingers of your guiding hand behind the safety fin 3. During working, the hand or fingers may not be held anywhere close to the saw blade.
• Never saw toward the direction of the body.
• The use of cooling agents during sawing is not permitted.
• When sawing light building materials, observe the statutory provisions and the recommendations of the material suppliers.

Check wood, press boards, building materials, etc. for foreign objects such as nails, screws or similar, and remove them, if required. Fig. F: Switch the machine on and apply it to an edge of the workpiece to be sawn. Do not saw flat on the full surface of the workpiece. Use a piece of scrap wood for a precise start of the cut. Fasten the piece of scrap wood as stop at the requested cutting line and saw alongside of this edge.

Sawing Workpieces to Size

Mount the fine cutting saw blade. Switch the machine on and apply it to the edge of the workpiece to be sawn. Hold the power tool at an inclined angle (approx. 60°). Fig. G: Observe the correct sawing direction as shown in the figure. Avoid the tip of the saw blade from plunging in (danger of kickback). Pay attention that the tip of the saw blade can extend freely out of the workpiece. Fig. H: Saw profile strips beginning from the edge as shown in the figure, and not from the rounded section. At the end of the cut, reduce the pressure on the saw blade in order to prevent fraying of the workpiece. After sawing, switch the power tool off immediately.

Working with the Cross-cutting Table

The power tool must not be operated with commercially available miter boxes. Using the Bosch cross-cutting table 14 intended for the power tool enables its stationary use as a chop saw, allowing for exact 90° cuts as well as for variable miter cuts to be performed. When using the cross-cutting table, always work with the fine cutting saw blade. For mounting the power tool onto and for working with the cross-cutting table 14, read and observe the operating instructions of the cross-cutting table.
