DeWalt DHS780 Original Instructions Manual page 42

EnGLISH
After several cuts are made at various mitre angles other than 0°, the platform may weaken
and not properly support the work. Install a new, unused platform to the saw after presetting
the desired mitre angle.

CAUTION: Continued use of a platform with several kerfs may cause loss of material
control and possible injury.
MAINTENANCE

WARNING: To reduce the risk of serious personal injury, turn tool off and remove
the battery packs or power supply before transporting, making any adjustments,
cleaning, repairing, or removing/installing attachments or accessories. An
accidental start-up can cause injury.

WARNING: To reduce the risk of serious personal injury, DO NOT touch the sharp
points on the blade with fingers or hands while performing any maintenance.
DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the plastic
guard. The polycarbonate material used in the guard is subject to attack by certain chemicals.
Lubrication
Your power tool requires no additional lubrication.
Cleaning
Before use, carefully check the upper guard, lower guard and dust duct to determine that they
will operate properly. Ensure that chips, dust or workpiece particles do not block of one of
the functions.
In case of workpiece fragments jammed between the saw blade and guards, disconnect the
machine from the power supply and follow the instructions given in Changing or Installing a
New Saw Blade. Remove the jammed parts and reassemble the saw blade.
Periodically clean all dust and wood chips from around AND UNDER the base and the
rotary table.

WARNING: Blow dirt and dust out of the main housing with dry air as often as dirt is seen
collecting in and around the air vents. Wear approved eye protection and approved dust
mask when performing this procedure.

WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic
parts of the tool. These chemicals may weaken the materials used in these parts. Use a
cloth dampened only with water and mild soap. Never let any liquid get inside the tool;
never immerse any part of the tool into a liquid.

Cleaning the Corded Power Supply Receptacle (Fig. D)

WARNING: Blow debris out of the corded power supply receptacle
To minimize the risk of eye injury, always wear eye protection and respiratory protection
when performing this.
Dust Duct Cleaning
Depending on your cutting environment, saw dust can clog the dust duct and may prevent
dust from flowing away from the cutting area properly. With the battery pack or corded power
supply removed and the saw head raised fully, low pressure air or a large diameter dowel rod
can be used to clear the dust out of the dust duct.
XPS™ LED Worklight Cleaning
For the best worklight performance, perform the following maintenance regularly with the
battery or corded power supply removed.
• Carefully clean saw dust and debris from worklight lens with a cotton swab.
• DO NOT use solvents of any kind, they may damage the lens.
• Dust build-up can block the worklight and prevent it from accurately indicating the line
of cut.
• Follow mitre saw's instruction manual to remove and install blade.
• With blade removed from saw, clean pitch and build-up from blade. Pitch and debris can
interfere with the worklight and prevent it from accurately indicating the line of cut.
