SECTION 1: SAFETY For Your Own Safety Read Instruction Manual Before Operating This Equipment The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words which are 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.
7. ONLY ALLOW TRAINED AND PROPERLY SUPERVISED PERSONNEL TO OPERATE MACHINERY. Make sure operation instructions are safe and clearly understood. 8. KEEP CHILDREN AND VISITORS AWAY. Keep all children and visitors a safe distance from the work area. 9. MAKE WORKSHOP CHILD PROOF. Use padlocks, master switches, and remove switch keys. 10. NEVER LEAVE WHEN MACHINE IS RUNNING. Turn power OFF and allow all moving parts to come to a complete stop before leaving machine unattended. 11.
Additional Safety Instructions for Laminate Trim Routers 1. READ THE ENTIRE MANUAL: This manual contains proper operating instructions for this router. 2. SAFETY EQUIPMENT: Wear safety glasses, respirator, and hearing protection when operating a router. 3. POWER SOURCE: Unplug the router and make sure the switch is OFF before inserting or removing bit, making adjustments, or performing maintenance or service. DO NOT make adjustments while the router is running. 4.
Electrical Safety Extension Cords We do not recommend the use of extension cords, if you find it absolutely necessary: • Use at least a 16 gauge cord that does not exceed 100 feet in length! • The extension cord must also contain a ground wire and plug pin. • DO NOT use an extension cord that has cuts, exposed wires, bent/missing prongs, or other damage. • A qualified electrician MUST size cords over 100 feet long to prevent motor damage.
SECTION 2: OPERATIONS Unpacking/Inventory The Model H7790/H7791 was carefully packed when it left our warehouse. If you discover the tool is damaged after you have signed for delivery, please immediately call Customer Service at (570) 5469663 for advice. Save the box and all packing materials for possible inspection by the carrier or its agent. Otherwise, filing a freight claim can be difficult. When you are completely satisfied with the condition of your shipment, you should inventory the contents.
Adjusting Bit Depth Unplug the router and make sure the switch is OFF before inserting or removing bit, making adjustments, or performing maintenance or service. DO NOT make adjustments while the router is running. To adjust the bit depth: 1. UNPLUG THE ROUTER AND MAKE SURE THE SWITCH IS OFF! 2. Loosen the lock knob shown in Figure 4 and adjust the base to approximately the desired height.
Routing Operations Once the router bit is installed, the depth is set, and the feed direction is determined, it is time to start routing. Routing Tips • Performing routing operations in multiple passes produces smoother results with less chance of “chip out” and burning of the workpiece. It also reduces the possibility of the router jerking out of your hands from trying to remove too much material in one pass. • Cutting end grain with the router will cause tearout.
Curved Trim Guide Straight Guide The curved trim guide is used for trimming curved surfaces, such as adding a decorative edge to a round table or trimming curved corners on a laminate countertop. The straight guide can be used for trimming, cutting dadoes, straight dovetails, and for cutting circles. This guide is only necessary with router bits that do not have a guide bearing. The bushing in the curved trim guide rides along the edge of the workpiece guiding the router bit.
To use the straight guide for interior cuts. To use the straight guide for cutting circles. 1. Set up the straight guide as explained for trimming, but adjust the guide to allow the router bit to follow an interior slot. 1. Set up the straight guide as shown in Figure 9 with the guide plate facing up. Note: When cutting interior slots, the router will tend to wander toward the guide. Keep a constant pressure towards the workpiece, and pull the router towards you, instead of pushing the router.
Template Guide The template guide allows the router to follow a template or pattern. This setup is necessary when routing interior slots where a bit with a guide bearing will not fit. To install the template guide: 1. Remove the screws securing the bottom of the router base as shown in Figure 10. Guidelines for building the template: 1. MDF is the most common template material, but the template can be made out of any material that is flat on the top and bottom, and is at least 3⁄16" thick. 2.

SECTION 4: MAINTENANCE Router Maintenance Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury. Router maintenance is simple. Keep the router free from dust, dirt and grease and always store it in a dry place. Plastic parts can easily be cleaned with a damp cloth, but never use water to clean any electrical parts. Solvents should also be avoided on plastic because of the possibility of damage.
