SECTION 1: SAFETY For Your Own Safety, Read Instruction Manual Before Operating This Machine The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that safety messages by themselves do not eliminate danger and are not a substitute for proper accident prevention measures.
WEARING PROPER APPAREL. Do not wear clothing, apparel or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to reduce risk of slipping and losing control or accidentally contacting cutting tool or moving parts. HAZARDOUS DUST. Dust created by machinery operations may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material.
Additional Safety for Router Tables Serious cuts, amputation, entanglement, or death can occur from contact with spinning bit. Improperly secured bits or spindle parts/fasteners can fly off and strike nearby operators or bystanders with great force. Flying dust or debris from cutting operation can cause eye injuries or blindness. To minimize risk of getting hurt or killed, anyone operating router MUST completely heed hazards and warnings below. AVOIDING AMPUTATION.
SECTION 2: POWER SUPPLY Availability 110V Circuit Requirements Before installing the machine, consider the availability and proximity of the required power supply circuit.

Loosen (4) cap screws that secure clamp block to slide block (see Figure 36).
Connecting Power Cords Leveling Router Table To reduce risk of injury from accidental contact with spinning router bit, ALWAYS make sure router table is placed on a flat, clean surface and then leveled before router operations. The Model T28780/T28781 includes an electrical box with a 110V receptacle and an ON/OFF paddle switch (see Figure 39). The router power cord can be plugged directly into the electrical box, and the power cord on the electrical box can be plugged into a 110V outlet.
Dust Collection This machine creates a lot of wood chips/ dust during operation. Breathing airborne dust on a regular basis can result in permanent respiratory illness. Reduce your risk by wearing a respirator and capturing the dust with a dust-collection system. Recommended CFM at Dust Port: 400 CFM Do not confuse this CFM recommendation with the rating of the dust collector.
To test run router table: 1. Clear all setup tools away from router table. 2. Make sure router table paddle switch is set to OFF position. 3. Make sure router power cord is plugged into receptacle in router table electrical box. 4. Connect router table power cord to power supply. 5. Reach into dust box and turn router ON. 6. Using paddle switch, turn router table ON, verify router powers up, and then turn router table OFF. 7. 8. Try to start router with paddle switch.
SECTION 4: OPERATIONS Operation Overview To reduce your risk of serious injury, read this entire manual BEFORE using machine. Eye injuries, respiratory problems, or hearing loss can occur while operating this tool. Wear personal protective equipment to reduce your risk from these hazards. To complete a typical operation, the operator does the following: 1. Examines workpiece to make sure it is suitable for cutting. 2.
Disabling Switch The switch can be disabled by removing the key, as shown below. Disabling the switch in this manner can prevent unauthorized operation of the machine, which is important if it is not kept inside an access-restricted building or in a location where children may be present. Stock Inspection Requirements Always follow these rules when choosing and routing stock: • DO NOT cut stock that contains large or loose knots.
• Scrape all glue off the workpiece before jointing. Glue deposits on the workpiece, hard or soft, will gum up the router bit, produce poor results, and increase the risk of kickback. Squaring Fence & Table • Remove foreign objects from the workpiece. Make sure that any stock you process with the router is clean and free of dirt, nails, staples, tiny rocks, or any other foreign objects that could damage the router bit and be thrown from the machine with significant speed/force.
Adjusting Fence The fence assembly on the Model T28780/ T28781 has an infeed fence and an outfeed fence. These can be moved side to side to increase or decrease the space around the router bit. The infeed/outfeed fences are secured to the fence base with T-bolts and steel knobs (see Figure 46). Use these knobs to loosen or tighten the infeed/ outfeed fences against the base.
Adjusting Router Height The Model T28780/T28781 is equipped with a manually operated router lift that can be adjusted via the index ring in the mounting plate. 5. Underneath mounting plate, tighten lock screw jam nut (see Figure 49) against plate to secure position. Jam Nut Lock Screw To adjust router height: 1. DISCONNECT MACHINE FROM POWER! 2. Insert crank handle into index ring (see Figure 48) on mounting plate. Rocker Arm Figure 49. Location of lock screw components.
Edge Jointing 6. Jointing the edge of a board requires a straightcutting router bit to remove wood from the face of the board. The result is a perfectly flat and square edge. Place straightedge against outfeed fence, then adjust fence base so straightedge is also against bit flute (see Figure 51). Top View Straight Router Bit (Enlarged) Bit Flute Spacer Always feed workpiece against router bit rotation direction, as illustrated below.
Profile Routing To cut a profile into a workpiece: 1. DISCONNECT MACHINE FROM POWER! 2. Secure bit in router according to router manufacturer's instructions. 3. Raise router bit to desired height, then adjust fence so it sits behind the bit the same distance as desired depth-of-cut (see Figure 53). Top View Infeed Fence Outfeed Fence Bit Routing Small Stock Feeding small stock past the router bit increases the risk of kickback from the workpiece slipping into the space between the fence and bit.
Free-Hand Routing ALWAYS use hold-downs or featherboards and push sticks when shaping small or narrow stock. These devices keep your hands away from spinning router bit and sufficiently support stock to allow a safe and effective cut, reducing risk of personal injury. 6. Secure zero-clearance fence board and router bit guard to fence base, then make sure fence is parallel with table T-slot (see Squaring Fence & Table on Page 31). 7.
ALWAYS use an auxiliary jig and extreme care when free-hand routing. Routing without fence and router bit guard greatly increases risk of accidental contact with spinning router bit, causing serious personal injury. 3. Remove fence from table. 4. If possible, fabricate and mount a custom guard over the bit that safely protects your hands from spinning router bit. 5. Insert starting pin in hole on mounting plate (see Figure 57) or clamp a starting block to table (see Figure 56). To free-hand rout: 1.
