Removing The Blade; Installing A Blade - DeWalt DCS777 Manual

Assembling the Base Extension Handles (Fig. V)

WARNING: Base extension handles must be assembled to both
sides of the saw's base before using the saw.
1. Locate the holes above the hand indentations on the side of the base.
2. Assemble the base extension handles
nuts 47 provided, as shown in Figure V.
3. Tighten securely with the hex wrench included with your saw.
4. Ensure the extension is secure by pulling on it to verify no movement.
5. Repeat steps 1 through 4 on the other side.
Inserting and Removing the Battery Pack from the
Tool (Fig. A–C)
nOTE: Make sure your battery pack
To Install the Battery Pack into the Tool
1. Align the battery pack 25 with the rails inside the tool's handle (Fig. A).
2. Slide it into the handle until the battery pack is firmly seated in the tool
and ensure that you hear the lock snap into place.
To Remove the Battery Pack from the Tool
1. Press the release button 26
tool handle.
2. Insert battery pack into the charger as described in the charger section
of this manual.
Fuel Gauge Battery Packs (Fig. C)
Some D WALT battery packs include a fuel gauge which consists of
e
three green LED lights that indicate the level of charge remaining in the
battery pack.
To actuate the fuel gauge, press and hold the fuel gauge button
combination of the three green LED lights will illuminate designating the
level of charge left. When the level of charge in the battery is below the
usable limit, the fuel gauge will not illuminate and the battery will need to
be recharged.
nOTE: The fuel gauge is only an indication of the charge left on the battery
pack. It does not indicate tool functionality and is subject to variation based
on product components, temperature and end-user application.
Bench Mounting (Fig. B)
1. Holes are provided in all four feet to facilitate bench mounting.
20
Bolts with a diameter of 8 mm and 80 mm in length is suggested.
Always mount your saw firmly to prevent movement. To enhance the
portability, the tool can be mounted to a piece of 12.5 mm or thicker
plywood which can then be clamped to your work support or moved to
other job sites and reclamped.
2. When mounting your saw to a piece of plywood, make sure that the
mounting screws do not protrude from the bottom of the wood.
The plywood must sit flush on the work support. When clamping the
saw to any work surface, clamp only on the clamping bosses where
the mounting screw holes are located. Clamping at any other point will
interfere with the proper operation of the saw.
3. To prevent binding and inaccuracy, be sure the mounting surface is
not warped or otherwise uneven. If the saw rocks on the surface, place
a thin piece of material under one saw foot until the saw is firm on the
mounting surface.
Transporting the Saw (Fig. A, B)

ADJUSTMENTS

WARNING: To reduce the risk of serious personal injury, turn
machine off and disconnect battery pack before making any
adjustments or removing/installing attachments or accessories.
An accidental start-up can cause injury.
Your mitre saw was accurately adjusted at the factory. If readjustment
due to shipping and handling or any other reason is required, follow the
steps below to adjust your saw. Once made, these adjustments should
remain accurate.
Adjusting the Rails for Constant Cutting Depth
(Fig. A, B, F, G)
The blade must run at a constant cutting depth along the full length of the
table and must not touch the fixed table at the rear of the slot or at the front
of the rotating arm. To achieve this, the rails must be perfectly parallel to the
table when the saw head is fully depressed.
