Motor
Your D WALT tool is powered by a D
E
with the nameplate marking. Voltage decrease of more than 10% will cause loss of power and
overheating. All D WALT tools are factory tested; if this tool does not operate, check the power
E
supply.
COMPONENTS (Fig. 1)
A. Trigger switch/variable speed switch
B. Swivel head shear
C. Lock-on control button
D. Blade
Variable Speed Switch (Fig. 1)
To turn the tool ON, squeeze the trigger switch (A). To turn the tool OFF release the trigger.
Your tool is equipped with a variable speed switch which enables you to select the best speed
for a particular application. The farther you squeeze the trigger, the faster the tool will operate.
Use lower speeds for cutting tight curves or following precise guideline. Higher speeds are better
for gradual curves and straight line cuts. For maximum tool life, use lower speeds only for short
periods of time.
Lock-On Button (Fig. 1, 2)
WARNING: To reduce the risk of serious personal injury, be sure to release the switch
lock button before disconnecting the plug from the power supply. Failure to do so will cause the
tool to start immediately the next time it is plugged in. Damage or injury could result.
To lock the trigger in the on position for continuous operation, depress trigger, push up
the lock button, and gently release the trigger.
To release the locking mechanism, depress the trigger fully, then release it. Before using the
tool each time, be sure that the lock button release mechanism is working freely..
OPERATION
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect
tool from power source before installing and removing accessories, before adjusting or
when making repairs. To prevent inadvertant operation, lock the trigger switch when the
tool is not in use and when storing the tool.
For accurate work, always clamp or anchor the material to be cut. Line up one edge of the tool's
middle blade with the cutting line and advance blades into the material without forced effort or
unnecessary pressure. A little practice will enable you to determine what forward pressure gives
you the smoothest cutting. It is important to keep the lower surfaces of the side blades flat on
the material being cut (Fig. 5). When cutting curves, do not tilt the tool; keep the side blades
flat and level.The head of the shear will swivel to afford better access to the material. For best
cutting efficiency, keep blades sharp.
Disassembly and Assembly
To remove shear head from motor, loosen three cap screws (E) using the hex wrench (F)
provided. Remove shear head (B) by pulling head firmly forward. Slight twisting action may be
required if head does not slide off easily.
To remove cutter blades from shear head, remove three cap screws (E) from shear housing
(G). Be careful not to lose rear spacer bushing when removing middle cap screw. Remove
center blade (H) from housing by tapping blade gently towards the rear. The side knives (I) and
side spacers (J) will now drop out of the housing.
To remove eccentric bearing assembly from shaft, use an appropriate wrench to loosen
eccentric nut (K) by turning counterclockwise.
To install eccentric bearing assembly onto shaft, make sure the large, thin washer (L) is first
inserted over shaft. Screw eccentric bearing assembly onto shaft and tighten with appropriate
wrench. Lubricate bearing (N) with a good grade of bearing grease.
To install cutter blades into shear housing, place the side knives (I) and side spacers (J) into
position in the shear housing (H). Insert center cap screw through side knife and side spacer
with rear spacer bushing between them. Start cap screw into thread just enough to hold blades
in place. DO NOT TIGHTEN. Insert spacer bushing into hole in center blade and lubricate. Install
center blade into shear housing by tapping blade gently forward using a drift pin to line up hole
in center blade with forward holes in housing. Insert and tighten forward cap screw making sure
spacer bushing in center blade stays in position. Apply good grade of bearing grease to clevis
or yoke in center blade where it rides on the eccentric bearing assembly. Insert rear cap screw
into shear housing but do not completely tighten.
To install shear head assembly onto drive motor, make sure all cap screws are loosened
about 3 or 4 complete turns. Place shear head onto unit and alternately tighten cap screws
snugly to lock head assembly in place. It may be necessary to gently tap the shear head into
place if it does not readily slip onto the nose of the power unit.
Adjustment (Fig. 5, 6)
SWIVEL HEAD
To better accomodate safe cutting at any angle, the shear head can be repositioned by loosening
the three cap screws.
Once the screws are loosened, turn the shear head to the desired angle. Retighten the three cap
screws before installing battery pack.
To adjust the curl of waste material, the left side knife has elongated holes. Adjustment may be
necessary after changing blades or material being cut. Loosen cap screws and tap side knife
either forward or backward so that curl of waste does not hit shear housing or work material
while cutting.
MAINTENANCE
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect
tool from power source before installing and removing accessories, before adjusting or
when making repairs. To prevent inadvertant operation, lock the trigger switch when the
tool is not in use and when storing the tool.
Cleaning
WARNING: Blow dirt and dust out of all air vents with dry air at least once a week. Wear
proper ANSI Z87.1 (CAN/CSA Z94.3) eye protection and proper NIOSH/OSHA/MSHA
respiratory protection when performing this.
WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts
of the tool. These chemicals may weaken the plastic 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.
Lubrication
All ball bearings are factory lubricated to last the life of the tool. All sleeve and needle bearings
receive their lubrication from grease in the gear case. Clean and re-lubricate gear case yearly
or whenever servicing requires the gear case to be removed. Use type and quantity of grease
shown on the parts bulletin packed with your tool.
