Safe operating practices

Danger!

Before using the portable circular saw, read and follow:

– these operating instructions,
- the "Information on handling power tools" in the enclosed booklet (leaflet no. 315.915),
– the currently valid site rules and the regulations for the prevention of accidents.
This portable circular saw is state of the art and has been constructed in accordance with the acknowledged safety regulations. Nevertheless, when in use, the power tool may be a danger to life and limb of the user or a third party, or the power tool or other property may be damaged. The portable circular saw may be operated only if it is
– used as intended,
– in perfect working order.
Immediately repair any faults which impair safety.

Intended use

This portable circular saw

– is designed for industrial applications,
– is designed for cutting along and across all securely positioned metals, except stainless steel and hardened steel, with a straight cutting movement,
– is not designed for cutting wood,
– is designed for use with circular saw blades and accessories which are indicated in this manual or recommended by the manufacturer. Not permitted are abrasive wheels.

Safe operating practices

Danger!

• Keep children away from the power tool.
• If the power cord is damaged while the power tool is being used, do not touch the power cord. Immediately pull out the mains plug. Never use a power tool which has a defective power cord.
  – Before carrying out any work on the power tool, always pull out the mains plug.
  – Lay the power cord to the rear away from the power tool and keep it away from the rotating saw blade.
  – Never use this power tool for wet cutting.
• When using the power tool, wear ear protection and goggles!
  – Guide the power tool away from your body.
• Never work overhead.
• Ensure that the upper and lower sides of the cutting path are free from obstructions.
• Keep hand away from cutting area and the blade. Keep your second hand on auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade.
• Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.

• Adjust the cutting depth to the thickness of the workpiece.
  Less than a full tooth of the blade teeth should be visible below the workpiece.

• Never hold piece being cut in your hands or across your leg. Secure the workpiece to a stable platform.
  It is important to support the work properly to minimize body exposure, blade binding, or loss of control.

• Hold power tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord.
  Contact with a "live" wire will also make exposed metal parts of the power tool "live" and shock the operator.
• When ripping always use a rip fence or straight edge guide.
  This improves the accuracy of cut and reduces the chance of blade binding.
• Always use blades with correct size and shape (diamond versus round) of arbour holes.
  Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
• Never use damaged or incorrect blade washers or bolt.
  The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation.
• Before using the power tool and saw blade, check them for damage, imbalances and vibrations. Conduct a test run!
• Use only saw blades which have a permitted speed at least as high as the nominal speed of the power tool.
• Switch on the portable circular saw before guiding it towards the workpiece.
• Do not load the power tool to such an extent that it stops.
• When using the power tool, hazardous substances may be released.
  Take suitable precautions (e.g. wear a dust-proof mask).
  – Never saw materials which contain asbestos.
• Never saw light-weight metals which have a magnesium content greater than 80% . Risk of fire!

- If power tools are used outdoors or are exposed to extreme metal dust, connect via a residual-current-operated circuit-breaker (tripping current max. 30 mA).

- Mark the power tool with adhesive labels only. Do not drill any holes into the housing.

Causes and operator prevention of kickback:

- Kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece toward the operator;

- When the blade is pinched or bound tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator;

- If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jumb back toward the operator.

Kickback is result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below.

- Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces. Position your body to either side of the blade, but not in line with the blade.

Kickback could cause the saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions are taken.

- When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or kickback may occur.

Investigate and take corrective actions to eliminate the cause of blade binding.

• When restarting a saw in the workpiece, centre the saw blade in the kerf and check that saw teeth are not engaged into the material.
  If saw blade is binding, it may walk up or kickback from the workpiece as the saw is restarted.
• Support large panels to minimise the risk of blade pinching and kickback. Large panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel.
• Do not use dull or damaged blades. Unsharpened or improperly set blades produces narrow kerf causing expressive friction, blade binding and kickback.
• Blade depth and bevel adjusting locking levers must be tight and secure before making cut.
  If blade adjustment shifts while cutting, it may cause binding and kickback.
• Use extra caution when making a "plunge cut" into existing walls or other blind areas.
  The protruding blade may cut objects that can cause kickback.

Guard

- Check lower guard for proper closing before each use. Do not operate the saw if lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. If saw is accidentally dropped, lower guard may be bent. Raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut.

- Check the operation of the lower guard spring. If the guard and the spring are not operating properly, they must be serviced before use.

Lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.

– Lower guard should be retracted manually only for special cuts such as “plunge cuts” and “compound cuts”.
Raise lower guard by retracting handle and as soon as blade enters the material, the lower guard must be released. For all other sawing, the lower guard should operate automatically.
- Always observe that the lower guard is covering the blade before placing saw down on bench or floor.
An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in path. Be aware of the time it takes for the blade to stop after switch is released.

Damage to property!

The mains voltage and the voltage specifications on the rating plate (5) must correspond.

Noise and Vibration

The noise and vibration values have been determined in accordance with EN 60745. The a evaluated noise level of the power tool is typically:

– Sound pressure level: 98 dB(A);

– Sound power level: 109 dB(A);

- Uncertainty: K = 3 dB.

Total vibration value (when sawing metal):

- Emissions value: a _h=2,3m^2s Uncertainty: K=1.5 m/s

– Uncertainty: K = 1.5 m/s

Attention

The indicated measurements refer to new power tools. Daily use causes the noise and vibration values to change.

Notes

The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure. The declared vibration emission level represents the main applications of the tool.

However if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ.

This may significantly increase the exposure level over the total working period.

For a precise estimation of the vibration load the times should also be considered during which the power tool is switched off or even running, but not actually in use. This may significantly increase the exposure level over the total working period

Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

Caution

Wear ear protection at a sound pressure above 85 dB(A).
