Use an exploded view before any repair: it shows the exact placement of fasteners, spacers, and assemblies so reassembly matches factory geometry. For the 708-series sliding miter saw, this visual map clarifies how the motor housing aligns with the rail carriage, where the detent plate sits under the turntable, and how the guard linkage tracks blade movement.
Identify assemblies by function, not by guesswork. The saw breaks down into the drive unit, sliding rails, bevel pivot, fence set, and dust channel. A clear schematic labels each element with reference numbers that match service lists, letting you confirm compatible replacements, torque points, and washer orientation before loosening a single bolt.
Follow sequence cues to avoid misalignment. The exploded layout reveals the build order: base casting first, then the miter mechanism, followed by rails, head assembly, and safety cover. This order prevents rail bind, preserves square cuts, and keeps the blade brake wiring routed away from pinch zones.
Check revision notes and tolerances. Updated drawings flag superseded items such as revised bushings or upgraded springs. Cross-checking these notes with the visual breakdown helps select current components, confirm shim thickness, and maintain factory clearances after service.
DW708 Parts Diagram: Practical Reference for Identification and Replacement
Use an exploded view from the service manual to match each assembly by position, fastener count, and interface points before removal. This prevents mixing similar-looking hardware such as shoulder bolts and standard hex screws.
Identify wear items by function rather than name. For example, the drive belt is recognized by rib count and width; measure both with calipers and compare against the pulley profile. Bearings are verified by stamped codes on the shield (e.g., 6202, 6203) and shaft diameter, not by housing shape.
Electrical elements require label matching. Check voltage, amperage, and insulation class printed on the motor plate and switch body. Replace brushes only after confirming length below the service limit and uneven wear patterns that indicate commutator issues.
Alignment-sensitive assemblies demand reference marks. Scribe the original position of trunnions and fences, then confirm squareness with a machinist square after installation. Torque fasteners evenly; clamp bolts should be tightened incrementally to avoid frame distortion.
Consumables should be selected by material and duty cycle. Choose arbor washers with hardened steel faces, select springs by wire diameter and free length, and pick dust ports by outlet diameter to maintain airflow.
Document each step. Photograph subassemblies, tag connectors, and store removed hardware in labeled trays. After replacement, run a no-load test, listen for abnormal vibration, and verify brake engagement time before returning the tool to service.
Locating and Naming Individual DW708 Components by Diagram Callouts
Match each callout number on the exploded view to the physical assembly before disassembly, marking the housing with removable tape to prevent mix-ups during reinstallation.
Callout indices usually follow the assembly flow: base and fence elements appear first, then the pivot system, followed by the drive unit, guard system, and handle controls. This order helps identify where a numbered reference belongs without guessing.
Use the callout legend to record the official component name exactly as shown, then add a short functional note such as blade elevation lock or miter detent plate. This reduces errors when cross-checking stock lists or service manuals.
Fasteners often share similar shapes but differ in thread pitch or length. Verify each screw or bolt by matching its callout number to the dimensional notes in the reference table, not by visual similarity.
Subassemblies like the motor carriage or bevel arm are typically grouped under consecutive callout ranges. Identifying these ranges speeds up tracing a single element back to its mounting location.
Electrical items use distinct callout symbols. Trace the numbering along the wiring path to confirm switch orientation, strain relief placement, and grounding points before removal.
Tip: Photograph the exploded view and annotate the image with your own notes tied to each callout. This creates a custom reference that mirrors the actual tool configuration on your bench.
Reading the Exploded View to Understand Assembly Order and Part Interaction
Follow the numbered callouts strictly from the base outward, assembling fixed elements before any moving ones.
Each exploded illustration communicates sequence and contact points through spacing, arrows, and index numbers. Treat distance between elements as the intended stacking order, not physical gaps.
- Identify the reference plane: frames, housings, or tables usually anchor the build and receive fasteners first.
- Read index numbers as sequence markers; lower numbers attach earlier unless arrows indicate a nested fit.
- Track fastener families separately: bolts, screws, pins, and clips often repeat with different lengths.
- Note washers, spacers, and bushings placed between rotating elements to prevent binding.
Pay attention to interaction cues that show how elements behave once assembled. Curved arrows imply rotation; straight arrows suggest sliding travel. Springs and detents signal preload direction and resting position.
- Group subassemblies visually by proximity; build these clusters off the main unit.
- Check orientation markers such as flats, keyways, or chamfers before tightening.
- Confirm mating surfaces align flush; offset shading usually marks overlap.
- Leave adjustment hardware loose until adjacent elements are seated.
Cross-reference quantities shown near callouts to avoid doubling or omission. If two identical elements appear mirrored, verify left/right orientation by comparing hole offsets or notch placement.
Finish by reviewing the illustration backward to confirm nothing blocks motion paths or service access points.
Aligning Reference Numbers with Compatible Replacement Components
Verify each reference number against the manufacturer’s service list before purchasing a substitute, matching both the numeric code and the revision letter stamped on the original component.
Cross-check the reference code with the official service manual table, then confirm voltage rating, amperage limit, and tolerance range; a mismatch in any of these metrics leads to premature failure.
Use exploded-view schematics to locate the exact position of the component and confirm adjacent assemblies; identical-looking items often differ by shaft length, thread pitch, or connector orientation.
Compare material specifications listed next to the reference number. For example, switching from sintered bronze to steel in a rotating element increases wear and noise, while polymer grades vary by heat resistance.
Check supersession notes in the service bulletin. A discontinued reference may map to a newer substitute with altered dimensions; confirm clearance using the stated millimeter offsets.
Validate compatibility through supplier cross-indexes. Reliable catalogs list direct-fit equivalents and flag near-matches that require shims, spacers, or wiring adapters.
Confirm fastener details tied to the reference code: torque value, thread class, and coating. Reusing mismatched hardware risks stripping or loosening under vibration.
Record the matched substitute alongside the original reference in your maintenance log to speed future servicing and prevent ordering errors.
