Festool ATF 55E User Manual

Instruction Manual 

17 

Any maintenance or repair work that requires opening of 

the motor or gear housing should be carried out only by an 

authorized Customer Service Center (name supplied by your 

dealer)! Maintenance or repair work carried out by an 

unauthorized person can lead to improper connection of 

electrical wires or other components, which can result in 

injury.  
To prevent injury or electrocution, always unplug the tool 

from the power supply outlet before performing any 

maintenance or repair work on the tool!  
Do not use compressed air to clean the motor housing of the 

tool, as you could inject foreign objects into the motor 

through the ventilation openings. Compressed air may be 

used on other components, but personal safety protection 

should be employed (hearing, vision, and respiratory). 
 Certain cleaning agents and solvents are harmful to plastic 

parts. Some of these include, but are not limited too: 

Gasoline, Acetone, Methyl Ethyl Ketone (MEK), Carbonyl 

Chloride, cleaning solutions containing Chlorine, Ammonia, 

and household cleaners containing Ammonia.  
To ensure proper cooling of the tool and motor, the cooling 

vents in the motor housing must always be kept clear and 

clean.  

Keep the Saw Clean 
Dust and debris from some materials can be extremely 

abrasive and cause components within the saw to wear 

prematurely. It is important to keep moving parts cleared of 

abrasive dusts. 

► 

As a general rule, keep the saw clean of all dust and 

debris. Even soft-wood dust can be abrasive over time. 

► 

Examine all moving parts for dust and debris.  

► 

Keep the bevel hinges  (figure 13) clean of dust using 

compressed air or cotton swabs. If the hinges wear due to 

abrasive particles, the saw will not perform optimally. 

► 

Keep the blade area and dust extraction ports clean of 

debris. Debris can cause wear and reduce the effectiveness 

of the dust extraction system. 

Keep the Sawblades Sharp 
Using a dull sawblade can be extremely dangerous and 

provide poor cut quality.  

► 

Never attempt to sharpen a sawblade manually. Special 

equipment is necessary to properly sharpen a circular 

sawblade. An improperly sharpened sawblade can injure 

the operator, destroy the saw, and damage the workpiece.  

► 

The sawblades should be sharpened regularly, and only 

by a qualified sharpening service. 

► 

Improper grinding of the carbide teeth of a sawblade can 

result in serious injury to the saw operator. 

 

Adjust and Inspect the Saw 
To ensure the saw is in proper working order, periodically 

inspect the operation of the saw and ensure it is properly 

adjusted. 

► 

Observe the function of the saw during normal operation.  

► 

Unusual sounds are indicative of pending problems.  

► 

A reduction in the cut quality indicates the saw is either 

improperly adjusted or not functioning properly. 

► 

A reduction in cutting power or speed may indicate a dull 

blade or a motor problem. 

► 

If any of the safety devices on the saw are inoperable or 

disabled, immediately stop using the saw and have it 

serviced. 

► 

Periodically inspect the guide rail gibs for wear and 

proper adjustment. If the gibs are worn or misadjusted, the 

saw will not cut straight.
