3.3 Safety instructions
READ ALL INSTRUCTIONS!
Non-observance of the instructions listed below can cause electric shock, fire and/or serious injuries
.
Work area
- Children and adolescents are not allowed to operate this machine.
- When using the machine outdoors, the use of an earth leakage circuit breaker is recommended.
- Replace damaged cables or plugs immediately. To avoid safety hazards, only MAFELL or an authorized
MAFELL service workshop is allowed to replace parts.
- Prevent sharp kinks of the cable. Do not wrap the cable around the machine, especially when transporting
and storing the machine.
- Do not use this machine when you are tired, or under the influence of drugs, alcohol or medicaments. Be
aware of what you are doing. Stay alert and use common sense.
- Keep children and bystanders at a distance while you are operating the machine. Distractions can cause
you to lose control of the machine.
- Use eye protection, dust mask and hearing protection. Appropriate safety equipment, used
under proper conditions, will reduce the risk of injuries.
Instructions for service and maintenance:
- Cleaning the machine regularly, especially the adjustment elements and the guiding devices, is an important
safety factor.
- Ensure that only genuine MAFELL spare parts and accessories are used. Failure to do so will make
warranty claims and the liability of the manufacturer null and void.
- Prepare a periodic maintenance schedule for your machine. When you clean the machine, be careful
not to disassemble any part of the machine. Reassembling the machine bears the risk that internal
wires are routed incorrectly or pinched, or that return springs of the safety device are mounted
incorrectly. Certain cleaning agents, such as gasoline, carbon tetrachloride, ammonia, etc. can damage
plastic parts.
- Some of the dust produced by sawing, sanding, drilling and other building work 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,
- Arsenic and chromium from chemically treated wood.
Your risk from this hazard varies with the frequency at which you perform this type of work. To reduce your
exposure to these chemicals: Work in a well-ventilated area. Work only with approved safety equipment,
such as dust masks that are specially designed to filter out particles of microscopic size.

3.4 Specific safety rules
Sawing method
- Keep your hands away from cutting area and saw blade. Hold the auxiliary handle or the motor
housing with your second hand. If both hands hold the saw, they cannot be injured by the saw blade.
Fig. 3: Incorrect sawing vs. correct sawing
- Do not reach underneath the workpiece. Below the workpiece, the guard cannot protect you from the saw
blade.
- Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth height should be
visible below the workpiece.
- Never hold the workpiece in your hands or across your leg while you are cutting it. Secure the
workpiece on a stable support. It is important to secure the workpiece safely. This minimizes the risk of
body contact, jamming of the saw blade or loss of control over the machine.
- Hold the machine by the insulated grip surfaces when you perform work that involves a risk of the
cutting tool hitting hidden power lines or its own power cord. Contact with a live line also energizes the
metallic parts of the machine, causing an electric shock.
- Always use a fence or straight edge guide for ripping. This improves the cutting accuracy and reduces
the possibility of the saw blade jamming.
- Always use saw blades of the correct size and with a suitable arbor hole (e.g. diamond-shaped or
round). Saw blades that do not match the mounting parts of the saw will run out of true, resulting in a loss of
control.
- Never use damaged or wrong saw blade washers or bolts. The saw blade washers and bolts are
designed specifically for your saw, for optimal performance and operational safety.

Kickback - causes and related safety instructions
- Kickback is the sudden reaction resulting from a pinched, jammed, or misaligned saw blade that causes an
uncontrolled saw to lift off and move out of the workpiece toward the operator.
- If the saw blade is pinched or jammed in the closing kerf, it will stall and the motor power will kick the saw
back toward the operator.
- If the saw blade is twisted or misaligned in the saw cut, the teeth of the rear edge of the saw blade can get
pinched in the wood surface, causing the saw blade to move out of the kerf and the saw to jump back
toward the operator.
Fig. 4: Kickback of the machine
Kickback is the result of incorrect or improper use of the saw. It can be prevented by taking appropriate
precautions, as described below.
- Hold the saw firmly with both hands. Position your arms such that you can withstand kickback
forces. Be sure that you are always positioned such that the saw blade is at the side of your body,
never in line with it. In the event of a kickback, the circular saw can jump backward. However, the operator
can take appropriate precautions to control the kickback forces.
- If the saw blade jams or when you stop working, switch off the saw and hold it steady in the material
until the saw blade is stopped. Never try to remove the saw from the workpiece or pull it backwards
as long as the saw blade is moving. This can cause a kickback. Determine and eliminate the cause of
jamming of the saw blade.
- To restart a saw that sits in the workpiece, center the saw blade in the kerf and ensure that the saw
teeth are not jammed in the workpiece. A jammed saw blade can move out of the workpiece or cause a
kickback when the saw is restarted.

K65cc/KSS60cc
01/2022
11
- Support large panels to reduce the risk of a kickback from a jammed saw blade. Large panels tend to
sag under their own weight. Panels must be supported on both sides: near the kerf and at the edge.
Fig. 5: Incorrect support vs. correct support
- Never use blunt or damaged saw blades. The kerf produced by a saw blade with blunt or incorrectly
aligned teeth is too narrow, causing increased friction, jamming of the saw blade and kickback.
- Prior to starting sawing, tighten the cutting depth and cutting angle settings. If the settings change
during the sawing process, there is a risk of a jamming saw blade and kickback.
- Be particularly careful when sawing into existing walls or other concealed areas. The saw blade can
jam and cause kickback when cutting into hidden objects.
Function of the lower guard
- Before each use, ensure that the guard is closed properly. Never use the saw if the guard cannot
move freely and does not close instantly. Never clamp or tie the guard. This would leave the saw
blade unprotected. The guard can be bent if the saw drops to the ground. Ensure that the guard moves
freely and does not get in contact with the saw blade or other parts at all cutting angles and cutting depths.
- Check the function of the spring for the lower guard. Have the saw serviced before use if lower
guard and spring do not function properly. Damaged parts, sticky deposits or accumulations of chips
delay the operation of the lower guard.
- Open the lower guard manually only to perform special cuts, such as "plunge cuts" or "compound
cuts". Open the lower guard with the retracting lever. Release the lever as soon as the saw blade
penetrates the workpiece. For all other sawing operations, the lower guard should operate automatically.
- Ensure that the lower guard covers the saw blade when you put the saw down on the workbench or
on the floor. An unprotected coasting saw blade moves the saw against the direction of cut and cuts
whatever is in its way. Be aware of the coasting time of the saw blade.

K65cc/KSS60cc

Function of the riving knife
- Always use the saw blade that is suitable for the riving knife. The riving knife is only effective if the body
of the saw blade is thinner than the riving knife and the tooth width is greater than the thickness of the riving
knife.
- Adjust the riving knife as described in these operating instructions. Incorrect spacing, position and
alignment can be the reason that the riving knife can not prevent kickback efficiently.
- Always use the riving knife, with the exception of "plunge cuts". Mount the riving knife back on after
the plunge cut. The riving knife interferes with plunge cuts and can cause kickback. This section only applies
to hand-held circular saws without a pivoting riving knife (known as MAFELL flip knife). The flip knife retracts
into the machine during a plunge cut.
- To be effective, the riving knife must be in the kerf. In short cuts, the riving knife is ineffective for
preventing kickback.
- Never operate the saw with a bent riving knife. Even a minor malfunction can slow down the closing of
the guard.
