GENERAL SAFETY RULES

WORK AREA

1. 1. ALWAYS keep the work area clean and well lit. Cluttered and dark areas invite accidents.
   2. DO NOT operate power tools in explosive atmospheres such as in the presence of flammable liquids, gasses or heavy dust. Power tools create sparks which may ignite dust or fumes.
   3. ALWAYS keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

1.  Power tools must match the power outlet. NEVER modify the plug in any way. DO NOT use adaptor plugs with earthed (grounded) power tools. Correct plugs and outlets will reduce the risk of electric shock.
2.  DO NOT expose power tools to rain or wet conditions. Any water entering power tools will increase the risk of electric shock.
3.  DO NOT abuse the electrical cable. NEVER use the cable for pulling or unplugging the power tool. Keep the cable away from sources of heat, oil, sharp edges or moving parts. Damaged or tangled cables increase the risk of electric shock.
4.  If working outdoors, use outdoor extension leads, always use an approved cable extension suitable for the power rating of this tool (see specifications). The conductor size should also be at least the same size as that on the machine, or larger. We strongly recommend that this machine is connected to the mains supply via a Residual Current Device (RCD).

PERSONAL SAFETY

1.  Stay alert, watch what you are doing and use common sense when you are operating a power tool. DO NOT operate a power tool when you are tired, ill or under the influence of alcohol, drugs or medication.
2.  Wear personal protective equipment including eye protection. Safety equipment such as a dust mask, non-skid shoes and hearing protection used for appropriate conditions will reduce personal injuries. Use a face or dust mask if operation is particularly dusty. Wear ear protectors/defenders as the noise level of this machine can exceed 85dB (A).
3.  DO NOT over-reach. Keep a proper footing and balance at all times. This enables better control of the power tool in unexpected situations
4.  Concentrate on the job in hand, no matter how trivial it may seem. Be aware that accidents are caused by carelessness due to familiarity.
5.  Dress appropriately. DO NOT wear loose clothing or jewelry which may get caught in moving parts. Wear protective hair covering to contain long hair. For best footing, wear rubber soled footwear. Keep floor clear of oil, scrap wood, etc.
6.  AVOID accidental starting of the machine. Ensure the switch is in the off position and the locking button disengaged before plugging the machine in to the power supply. Carrying power tools around with your finger on the trigger or plugging in power tools that are switched on invites accidents.
7.  Switch the machine OFF immediately after the task is completed.

POWER TOOL USE AND CARE

1.  DO NOT force the machine. Use the correct power tool for your application. It will do a better and safer job at the rate for which it was designed.
2.  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.
3.  Disconnect the power tool from the power supply before making any adjustments, changing accessories, or storing the tool. These measures will reduce the risk of the power tool starting accidentally.
4.  Store power tools out of the reach of children and DO NOT allow persons unfamiliar with these instructions to operate the power tool. Power tools are potentially dangerous in the hands of untrained users.
5.  Use recommended accessories. The use of improper accessories could be hazardous.
6.  Machine cleanliness. DO NOT allow the ventilation slots in the machine to become blocked with dust.
7.  Check the power tool for damage before using the machine each time. Any damaged part should be inspected to ensure that it will operate properly and perform its intended function. Check for alignment of moving parts, breakage of parts, mountings, and any other condition that may affect the machine’s operation. Any damage should be properly repaired or the part replaced. If in doubt, DO NOT use the machine. Consult your local CLARKE dealer.

SERVICE

1.  When necessary, have your power tools serviced or repaired by a qualified person using identical replacement parts. This will ensure that the safety of the power tool is maintained

RECIPROCATING SAW SAFETY INSTRUCTIONS

WARNING: ONLY USE THE SAW AS DESCRIBED IN THESE INSTRUCTIONS.

HAND VIBRATION
All hand held power tools vibrate to some extent, and this vibration is transmitted to the operator via the handles. Operators who are regularly exposed to vibration may suffer from Hand Arm Vibration Syndrome (HAVS), which includes ‘dead hand’, ‘dead finger’, and ‘white finger’. These are painful conditions and are widespread in industries where vibrating tools are used. If you feel numbness or pain in hands or arms, STOP using the tool and take a rest. If symptoms persist seek medical advice.

CHANGING BLADES (PAGE 9)

1.  Unplug the saw before changing blade and take care to prevent entrapment of fingers between the blade and the shoe. Ensure the blade is secure before use.
2.  Use the appropriate saw blade for the material being cut. Different blades are available from your CLARKE dealer.
3.  Only use saw blades in perfect working condition. Discard and replace any cracked or bent saw blades.

WHEN SAWING (PAGE 12)

1.  Keep the mains cable well away from the saw blade and ensure an adequate electrical supply is close at hand so that the operation is not restricted by the length of the cable.
2.  Working on the bench. Allow sufficient clearance beneath the workpiece to ensure the blade does not come into contact with the floor, bench etc.
3.  Switching off. NEVER place the saw on a table or bench if it has not completely stopped. The saw blade will continue to reciprocate for a short time after the trigger has been released to stop the saw.
4.  DO NOT cut material above the specified thickness.
5.  Cutting into walls. DO NOT cut through walls or cavities before checking for hidden electrical wires or water pipes etc.
6.  Finishing cutting. DO NOT remove the tool from the work until the blade has completely stopped and allow time for it to cool before touching the blade immediately after use. 7. Use clamps & vices wherever possible to secure the workpiece.

SAFETY SYMBOLS

OVERVIEW

The CLARKE CRS710B is a variable-speed reciprocating saw fitted with a lockon button for continuous operation. The saw is equipped with a quick release blade retention system for convenient replacement of saw blades. When unpacking, check for damage or shortages etc. Any found should be reported to your CLARKE dealer where the appliance was originally purchased. This CRS710B Reciprocating Saw is supplied with the following components:

The saw is also supplied with the following cutting blades:

• 2 x 130mm Wood Cutting Blade
• 1 x 80mm Metal Cutting Blade

BEFORE USE

CAUTION: USE ONLY RECIPROCATING SAW BLADES WITH THE CORRECT FITTING AS SHOWN BELOW. ALWAYS ENSURE THE SAW IS DISCONNECTED FROM THE POWER SUPPLY BEFORE INSTALLING/REMOVING THE BLADE

INSTALLING/CHANGING BLADES

1.  Twist the quick release chuck a 1/4 turn anti-clockwise and hold open.
2.  Insert or remove the blade while keeping the chuck open.
   • Never use cracked, blunt or otherwise damaged blades.
3.  Release the chuck when the blade is fully inserted in position, making sure the teeth of the blade are pointing downwards. The blade will now be locked in place.
4.  Pull the blade to check that it is secure. If it does not pull out, it is correctly fitted.

ADJUSTING THE GUIDE SHOE

WARNING: ALWAYS ENSURE THE SAW IS DISCONNECTED FROM THE POWER SUPPLY BEFORE MAKING ADJUSTMENTS.

1.  To adjust the shoe, unlock by releasing the locking lever on the side of the saw. Adjust the shoe to the desired position and then push the locking lever back into position.
   • Note that the shoe can slide fully in and out of the saw body.
2.  The head of the shoe will adapt to the surface of the workpiece you are working on with an inclination of up to 30o

ADJUSTING THE HANDLE
The handle can be rotated 90o left or right of centre so as to give a better angle of attack on the workpiece.

1.  Press and hold the handle locking switch.
2.  Rotate handle 90o left or right, depending on angle of attack needed.
3. Release handle locking switch to lock the handle into place.

OPERATION

IMPORTANT: DO NOT plug into the mains, unless you have ensured the saw is switched OFF. To do this, squeeze the trigger fully, then release it.

PRIOR TO CUTTING

1. Ensure that the workpiece is securely held in place and that the cut line is clearly marked.
2.  Ensure the blade is not striking anything below the workpiece and that the power cable is well away from the moving blade before starting the saw.
   • Let the blade work naturally. If cutting out an aperture, it will be necessary to drill a suitably sized hole in the workpiece to use as a starting point.
   • The blade should emerge from the work at every point of the cut.
3.  Check that any previously used timber being sawn does not contain any nails or other metal objects which would damage the blade.

STARTING & STOPPING

1.  To start the saw, squeeze the trigger.
2.  Maintain the saw at a constant speed by pressing in the lock button.
   • You can then release your finger pressure on the trigger.
3.  To stop the saw if the lock button is used, squeeze the trigger fully in, then release it and the motor will stop. Always switch off before unplugging.

USING THE SAW

1.  Place the shoe fully against the work-piece and squeeze the trigger to run the saw before letting the blade touch the cut line on the work piece. To make your cut, move the saw slowly along the cutting line.
2.  Take care not to allow the saw to bounce on the workpiece. Ensure the shoe remains in contact with the workpiece.
3.  Always hold the saw with both hands on the body and handle.
4.  Take extra care when cutting curves – move slowly to avoid stress on the blade.
5.  Avoid putting unnecessary pressure on the blade and avoid applying lateral pressure. Let the blade work naturally.
6.  Never try to start the saw if the blade becomes jammed in the workpiece.
7.  If the blade becomes blunt in one section of its cutting edge, reposition the shoe to utilise a sharper, unused portion of the blade. Page 10 shows the adjustable shoe which can be positioned close to the blade holder and then extended to optimise the use of the blade & extend its useful life.

CUTTING DIFFERENT MATERIALS
Adjust the speed controller wheel to suit the material being cut using the following suggested settings as a starting point. However, the optimum speed will be determined with practice.

• Plastic: Slow – Medium
• Steel: Slow – Medium
• Hardboard: Medium
• Ceramics: Medium – Fast (max)
• Aluminium: Medium – Fast (max)
• Wood: Medium – Fast (max)

CUTTING WOOD

PLUNGE CUTTING IN WOOD

• Rest the saw shoe on the workpiece in such a position that the blade forms an appropriate angle for the plunge cut.
• Switch the saw on and slowly feed in the blade. Make sure that the saw shoe remains in contact with the workpiece at all times.

POCKET CUTS IN WOOD

• Measure and mark out the pocket cut. Using a narrow blade, rest the bottom of the shoe on the workpiece ensuring the blade is on the cutting line. If necessary, e.g. in confined spaces, use the outer edge of the shoe as your guideline.

CUTTING METAL

1.  Choose the correct blade for cutting metal. Support the workpiece with wooden blocks on either side.
2.  Apply a thin film of lubricant along the cutting line to prevent the tool from overheating.

CUTTING PLASTICS

• Always work at reduced speed and carry out a test cut to see if the material is sensitive to heat or vibration.

MAINTENANCE

CLEANING

1.  To ensure constant air circulation and after use, clean all dust and wood chippings from the reciprocating saw.
   • Clean all of the ventilation slots on the motor housing.
   • If possible, use compressed air to clean the machine (Always wear eye protection when using compressed air).
2.  The blade holder should be kept clean and occasionally be lightly oiled.
3.  Keep the handle clean and free from oil and grease.
4.  Resin and glue on the blade causes poor cutting results. Clean the blade after use if necessary.

GENERAL MAINTENANCE

1.  Check the power cable to ensure it is sound and free from cracks, bare wires etc. Avoid using solvents when cleaning plastic parts, most plastics are susceptible to damage from the various types of commercial solvents.
2.  Ensure all nuts, bolts and screws remain tight at all times.
   • All bearings etc, in this power tool are lubricated with a sufficient amount of high grade lubricant for the tools lifetime under normal operating conditions, therefore no further lubrication is required.
