WARNING:
Always switch OFF and disconnect the rotary tool from the power supply before car-
rying out any adjustments, service or maintenance.
IMPORTANT:
Servicing of the tool requires extreme care and knowledge and should be performed only by
a qualified service technician.
CLEANING AND INSPECTION
1. After each use, clean the tool and accessories using a clean cloth or a soft brush. NEVER use water or other
liquids to clean the electrical portions of the tool.
2. Keep the ventilation openings free from dust and debris to prevent the motor from overheating.
3. Check the tool and accessories for any damage. Remove and dispose of damaged accessories.
LUBRICATING THE FLEX SHAFT
The flex shaft’s inner coil rotates at high speed during operation, generating friction and heat. It is important to
lubricate the inner coil of your flex shaft after several hours of operation to prevent it from overheating.
To lubricate the flex shaft, pull the inner coil out from the flex shaft. Apply an even coat of multi-purpose grease
onto the entire surface of the inner coil. Insert the inner coil back into the flex shaft.
CARBON BRUSHES INSPECTION AND REPLACEMENT (Fig. 16 & 17)
MAINTENANCE
Carbon Brush
Length
To maintain efficiency of the motor, inspect the two carbon brushes
routinely. The wear on the carbon brushes depends on how fre-
quently and how heavily the tool is used. Replace the brushes when
the brush length gets down to 1/8 of an inch or when the tool stops
working.
NOTE: Replacement carbon brushes (Model 23114-010) can be
purchased from wenproducts.com. Only genuine WEN replace-
ment brushes designed specifically for your tool should be used.
1. The carbon brush caps are located on the top and bottom of the
rotary tool (Fig. 16). To access the brushes, unscrew and remove the
two brush caps using the end of the wrench included with your tool
kit.
2. Take out and inspect the carbon brushes (Fig. 17). If the brushes
are worn to under 1/8 inch in length, replace them with new carbon
brushes and reinstall the brush caps. Both carbon brushes should
be replaced at the same time. Fully tighten both brush caps with the
wrench.
