Safety Warnings for Dry Cut Saws

Dry Cut saws are intended for the cutting of various profiles of ferrous and non-ferrous materials using appropriate carbide tipped circular saw blades, they cannot be used with abrasive cut-off wheels. Abrasive dust causes moving parts such as the lower guard to jam.

The rated speed of the carbide tipped saw blade must be at least equal to the maximum speed marked on the dry cut saw tool. Accessories running faster than their rated speed can break and fly apart.

Do not use blades that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.

Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or metal swarf may fly away and cause injury beyond immediate area of operation.

Do not operate the dry cut saw near flammable materials. Do not operate the dry cut saw while placed on a combustible surface such as wood. Sparks could ignite these materials.

WARNING

Never cut magnesium with this tool.

Never support the workpiece by hand. Do not feed the workpiece into the blade or cut "free hand" in any way. The workpiece must be stationary and clamped against the vise stop, vise clamp, and the table. Do not use this saw to cut pieces that are too small to be securely clamped. Unrestrained or moving workpieces could be thrown at high speeds, causing injury. If you use your hand to support the workpiece, there is a risk of injury from blade contact.

All adjusting locking levers must be tight and secure before making the cut. If blade adjustment shifts while cutting, it may cause binding and kick-back.

Do not reach behind the vise stop with either hand from either side of the saw blade, to remove metal scraps, or for any other reason while the blade is spinning. The proximity of the spinning saw blade to your hand may not be obvious and you may be seriously injured.

Inspect your workpiece before cutting. If the workpiece is bowed or warped, clamp it with the outside bowed face toward the vise stop. Always make certain that there is no gap between the workpiece, vise stop and table along the line of the cut. Bent or warped workpieces can twist or shift and may cause binding on the spinning saw blade while cutting.

Do not use the saw until the table is clear of all tools, metal scraps, etc., except for the workpiece. Small debris or loose pieces of metal or other objects that contact the revolving blade can be thrown with high speed.

Ensure the dry cut saw is mounted or placed on a level, firm, and non-combustible work surface before use. A level and firm work surface reduces the risk of the dry cut saw becoming unstable.

Plan your work. Every time you change the miter angle setting, make sure the adjustable vise stop is set correctly to support the workpiece and will not interfere with the blade. Without turning the tool "ON" and with no workpiece on the table, move the saw blade through a complete simulated cut to assure there will be no interference or danger of cutting the fence.

Provide adequate support such as table extensions, sawhorses, etc. for a workpiece that is longer than the tabletop. Workpieces wider than the dry cut saw table can tip if not securely supported. If the cut-off piece or workpiece tips, it can lift the lower guard or be thrown by the spinning blade.

Do not use another person as a substitute for a table extension or as additional support. Unstable support for the workpiece can cause the blade to bind or the workpiece to shift during the cutting operation pulling you and the helper into the spinning blade.

The cut-off piece must not be jammed or pressed by any means against the spinning saw blade. If confined, i.e. using length stops, the cut-off piece could get wedged against the blade and thrown violently.

ALWAYS USE THE VISE OR SPECIAL FIXTURE TO CLAMP WORK SECURELY. Other aids such spring, bar, or C-clamps may be appropriate for certain sizes and shapes of workpiece. Use care in selecting and placing these clamps to avoid interference with the guard and blade. Make a dry run before making a cut.

Always use a clamp or a fixture designed to properly support round material such as rods or tubing. Rods and tubing have a tendency to roll while being cut, causing the blade to "bite" and pull the work into the blade.

Let the blade reach full speed before contacting the workpiece. This will reduce the risk of the workpiece being thrown.

Safety Warnings for Dry Cut Saws

If the workpiece or blade becomes jammed, turn the dry cut saw off. Wait for all moving parts to stop and remove the battery pack. Then work is free the jammed material. Continued sawing with a jammed workpiece could cause loss of control or damage to the dry cut saw. Investigate and take corrective actions to eliminate the cause of blade binding.

When restarting a saw in the workpiece, center the saw blade in the kerf so that the saw teeth are not engaged into the material. If a saw blade binds, it may walk up or kickback from the workpiece as the saw is restarted.

After finishing the cut, release the switch, hold the saw head down and wait for the blade to stop

before removing the cut-off piece. Reaching with your hand near the coasting blade is dangerous.

Hold the handle firmly when making an incomplete cut or when releasing the switch before the saw head is completely in the down position. The braking action of the saw may cause the saw head to be suddenly pulled downward, causing a risk of injury.

Avoid overheating the saw blade tips.

Regularly clean the power tool's air vents. The motor's fan can draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.

Additional Safety Warnings

GFCI and personal protection devices like electrician's rubber gloves and footwear will further enhance your personal safety.

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.

WARNING

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 chemically-treated lumber.

Before each use, review all warnings located on the dry

WARNING Wear Eye Protection

The operation of any power tool can result in foreign objects being thrown into the eyes, which can result in severe eye damage. Always wear safety goggles that comply with ANSI Z87.1 (shown on pack-

age) before commencing power tool operation.

Disposal

This section is part of Robert Bosch Tool Corporation's commitment to preserving our environment and conserving our natural resources.

Adjusting the Vise Stop

(Fig. 12)

The Vise Stop 6 can be adjusted to accommodate cross or chop cuts in standard profiles and steel stud bundles at 90°. It can also be adjusted to perform miter cuts between 0° and 45° in standard profile sizes. In the 0° setting, two capacity settings are available: standard profile and steel stud bundle. Miter cuts can only be performed when the Vise Stop 6 is set in the Miter Zone 45.

The Base 18 is marked with slots next to the Vise Stop 6 that serve as an alignment guide. When the Vise Stop 6 is positioned between slot A and B it supports 90° chop cuts in standard profile sizes. When the Vise Stop 6 is aligned with slot C it supports 90° chop cuts in banded steel stud bundles (the Steel Stud Setting 46).

The space between slot A and slot B is called the Miter Zone 45. When the Vise Stop 6 is set in the miter zone it can be adjusted to make miter cuts of up to 45°. Do not perform miter cuts outside of the designated miter zone area (the No Miter Zone 47).

WARNING Do not set the Vise Stop for miter cuts outside of the miter

zone. Upstroke cutting may occur when Vise Clamp is set for miter cutting outside of the miter zone. Upstroke of the blade tends to pull the workpiece up from the vise and may result in serious damage to the tool and possible personal injury.

Basic Saw Operations

Material Positioning and Clamping

(Fig. 1, Fig. 35, Fig. 36)

Position the Workpiece 42 so it will be cut on the downstroke of the Blade 24. Downstroke cutting occurs in front of the blade center line 48 while upstroke cutting behind the blade center line 49.

WARNING Use appropriate clamping to restrain vertical movement of the workpiece when upstroke cutting is possible. Upstroke of the blade tends to pull the workpiece up from the vise and may result in serious damage to the tool and possible personal injury.

- Long workpieces must be supported with an auxiliary workpiece support to prevent sagging.

- Always securely clamp the workpiece with the Vise Clamp 7 and Vise Stop 6. (See “Clamping the Workpiece” on page 24.)

Long Workpiece Support

(Fig. 37)

WARNING Do not use another person as a sub stitute for a table extension or as additional support. Unstable support for the workpiece can cause the blade to bind or the workpiece to shift during the cutting operation, causing you to contact the spinning blade.

WARNING Long workpieces have a tendency to tip over unless clamped down and properly supported from underneath.

Support long Workpieces 42 to prevent sagging.

Use an Auxiliary Workpiece Support 43 for long Workpieces 42, opposite the Cut-Off End 44.

Blocks – Long Workpieces 42 need extra support. The base height is 2-5/8" (66 mm). Cut two 2x4 pieces to 2-5/8" in length and fasten together. Boards of this thickness and height can be used to create auxiliary support extensions for long Workpieces 42.

Clamps - Other hold-down devices such as C-clamps can be used to hold the Workpiece 42 firmly against the Base 18 and the Vise Stop 6. Make sure the clamps are clear of the cutting path.
