This document describes the DEWALT DW744 Heavy-Duty 10" (254 mm) Job Site Table Saw, a robust tool designed for various cutting operations in a workshop or job site environment. The saw is primarily used for ripping (cutting with the grain) and crosscutting (cutting against the grain) wood and man-made materials. It features a 10" (254 mm) diameter saw blade and is built with safety and precision in mind, incorporating several guarding and adjustment mechanisms.

Function Description:

The DEWALT DW744 is a versatile table saw capable of performing straight cuts, bevel cuts, miter cuts, compound miter cuts, and dado cuts. Its core function is to provide accurate and repeatable cuts on various workpieces. The saw is equipped with a powerful motor to drive the 10" blade, allowing it to cut through different materials efficiently. The blade height and bevel angle are adjustable, enabling users to customize cuts according to project requirements. A rip fence is included for guiding material during ripping operations, ensuring straight and consistent cuts. For crosscutting, a miter gauge is provided to guide the workpiece at specific angles. The saw also supports dado cutting for creating grooves and dados, although this requires the removal of the blade guard assembly and the use of a special dado insert.

Usage Features:

The DW744 incorporates several features to enhance usability and safety during operation.

Rip Fence Operation: The saw features a rail lock lever (E) that securely locks the rip fence in place, preventing movement during cutting. A fine adjustment knob (D) allows for precise positioning of the fence, crucial for accurate ripping. The rip scale indicator (C) helps in setting the desired cut width. The rip fence can be adjusted for both standard ripping and narrow ripping operations. For narrow rips (2" or narrower), a narrow rip auxiliary fence (A13) is recommended, used in conjunction with a push block (A12) to safely guide the workpiece.
Work Support Extension: A retractable work support extension (T) is integrated into the saw to provide additional support for longer workpieces that extend beyond the main table surface. This helps maintain stability and accuracy when cutting large materials.
Blade Adjustments: The saw allows for easy adjustment of blade height and bevel angle. The blade height adjustment wheel (F) raises or lowers the blade, while the bevel lock lever (G) and bevel stop screw (RR) enable setting the blade at angles other than 0° for bevel cuts. The miter gauge (K) features adjustable stops at 90° and 45° left and right, allowing for precise miter cuts.
Guard System: A comprehensive guarding system is a key safety feature. This includes a blade guard assembly (M), a riving knife (O), and an anti-kickback assembly (P). The blade guard assembly covers the blade, while the riving knife helps prevent kickback by keeping the kerf open. The anti-kickback assembly further reduces the risk of kickback. These components are designed to be in place for most operations, especially through cutting. The guard system can be raised for visibility during measurement and then lowered to the operating position.
On-Off Switch: The saw is equipped with an easily accessible ON/OFF switch (I). A padlock hole (JJ) is provided on the switch for security, allowing the saw to be locked off to prevent unauthorized use.
Dust Collection: A dust collection port (Q) is included for connecting to a dust extraction system, helping to keep the work area clean and improve visibility during operation.
Bench Mounting: The saw can be firmly mounted to a workbench or a dedicated stand using the provided mounting holes (J). This ensures stability and prevents the saw from tipping over during use. DEWALT offers specific table saw stands (DW7440 and DW7440RS) designed for use with this model.

Maintenance Features:

Proper maintenance is essential for the longevity and safe operation of the DW744 table saw.

Blade Care: Saw blades should always be kept sharp and clean for best and safest performance. Instructions for lubricating and changing accessories are provided. It is recommended to use only 10" (254 mm) diameter saw blades designed for maximum safe operating speeds of 5,000 RPM or greater. A reputable sharpening service should be used when blades need sharpening. Blades should be stored properly, with material like cardboard between them to prevent contact.
Riving Knife Selection: The riving knife must be matched to the saw blade dimensions (body thickness and kerf width) to function effectively and prevent kickback. The manual provides guidelines for selecting the correct riving knife thickness and outlines a procedure for verifying its fit with the blade.
Checking for Damaged Parts: Before each use, the tool should be checked for damaged parts, including the guard system, alignment of moving parts, and any other conditions that might affect its operation. Any damaged parts should be repaired or replaced promptly. The switch should also be checked to ensure it turns the tool on and off correctly.
Cleaning: Keeping the work area clean is important for safety. The manual advises against operating electric tools near flammable liquids or in gaseous/explosive atmospheres.
Adjustments and Calibration: The saw is factory-adjusted, but readjustments may be necessary due to shipping, handling, or other reasons. The manual provides detailed instructions for adjusting the rip scale, blade alignment (parallel to miter slot), bevel stop and pointer, miter gauge, and fence alignment (parallel to fence). These adjustments ensure the saw maintains its accuracy over time.
Power Source Connection: Before connecting the saw to a power source, the switch must be in the OFF position. The power supply voltage should match the nameplate marking.
General Safety Practices: Regular checks of all safety components, such as the blade guard assembly, riving knife, and anti-kickback assembly, are crucial before each operation. The blade should be tight, and all lock knobs (bevel angle, height) should be secure. The fence lock lever should be tight and parallel to the blade for ripping, and the miter gauge knob should be tight for crosscutting.

The DEWALT DW744 is designed to be a reliable and safe tool when operated according to the instructions and safety guidelines provided in the manual.
