SHUT DOWN THE ENGINE, WAIT FOR ALL MOVING PARTS TO COME TO A COMPLETE STOP, REMOVE SPARK PLUG WIRE, DISCONNECT THE NEGATIVE BATTERY CABLE, THEN WAIT 5 MINUTES BEFORE PERFORMING ANY MAINTENANCE PROCEDURE OR INSPECTION ON THE CHIPPER.
Removing and Replacing the Engine Oil SHUT DOWN THE ENGINE, WAIT FOR ALL MOVING PARTS TO COME TO A COMPLETE STOP, REMOVE SPARK PLUG WIRE, DISCONNECT THE NEGATIVE BATTERY CABLE, THEN WAIT 5 MINUTES BEFORE PERFORMING ANY MAINTENANCE PROCEDURE OR INSPECTION ON THE CHIPPER. Tools and Supplies Needed • • • • • SAE 30 HD Oil Oil Filter Wrench 5/8" Wrench Suitable container for used oil Rags NOTE: Drain the oil when the engine is warm. Warm oil drains quicker and more completely. 1.
Tools Needed: • • • • Tape Measure Two 1/2" Wrenches 7/16" Wrench Straightedge Removing the Belt Belt Guard Hardware 1. Remove the eight Bolts, Lock Washers and Flat Washers from the Belt Guard using a 1/2" Wrench (Figures 26 and 27). 2. Remove the Belt Guard. 3. Remove the Locknut and Belt Guard Bracket (Figure 28). Belt Guard Figure 26 Belt Guard Hardware Figure 27 Locknut Belt Guard Bracket Figure 28 32 16.
4. Loosen the four Engine Bolts (two on the left side and two on the right side) using two 1/2" Wrenches, one on the Bolt and one on the Locknut underneath the Base (Figure 29). 5. Loosen the Adjusting nut on the Belt Tensioner using a 1/2" Wrench and slide the Engine away from you until the belt is loose enough to remove. 6. Engine Bolts Clutch Belt Remove the Belt from the Clutch and Sheave (Figure 30).
NOTE: Prior to retightening the Bushing Retaining Bolts, move the Sheave out approximately 1/8" from the straightedge to allow for compression of the Bushing during the tightening process. g) Slowly tighten the Bushing Retaining Bolts evenly and alternately (1/4 to 1/2 turn) starting with the Bolt farthest from the Bushing Saw Slot. h) Recheck the alignment after tightening the Bolts, and then retighten the Sheave Bushing Bolt. NOTE: Make sure that the Belt or Sheave is not hitting the Hopper. 5.
Inspecting the Chipper Knife and Wear Plate Routine inspection of the Chipper Knife and Wear Plate will ensure that your DR 16.50 FTP PRO Rapid Feed Chipper is operating at full efficiency (see “Regular Maintenance Checklist” at the beginning of this Chapter). Operating with a worn or damaged Chipper Knife or Wear Plate will cause extreme stress and vibration to the machine and make chipping difficult for the operator. THE HOPPER SHOULD BE SUPPORTED WHEN THE MOUNTING HARDWARE IS REMOVED.
4. Closely inspect the Chipper Knife and Wear Plate for nicks or dull (rounded) edges (Figure 35). 5. If necessary, repair or replace the Chipper Knife and/or Wear Plate per the following procedures. If the Knife and Wear plate do not need maintenance or adjustment, replace the Hopper. Chipper Knife Wear Plate Figure 35 Removing and Replacing the Chipper Knife BE CAREFUL AND WEAR GLOVES WHEN WORKING NEAR THE CHIPPER KNIFE. THE KNIFE EDGE CAN CUT YOU IF YOU COME IN CONTACT WITH IT.
8. Remove the dull or damaged Knife and visually inspect the Flywheel Slot and Knife mounting area and be sure they are clean and that the replacement Knife will be able to mount flush against the Flywheel. IF THE FLYWHEEL SURFACE IS NOT CLEANED PROPERLY AND THE CHIPPER KNIFE IS NOT MOUNTED FLUSH ON THE FLYWHEEL, THE KNIFE COULD CRACK WHEN THE HARDWARE IS TIGHTENED. 9.
Checking and Adjusting the Knife to Wear Plate Gap When you replace the Knife you must check and set the clearance between the Knife and Wear Plate. Set this clearance or gap to 1/16" by using the Gap Tool that is supplied with the Chipper and with a new Knife kit. If the gap between the Wear Plate and the Knife is not set correctly, you will have excessive vibration when chipping and the Knife will seem to be dull. The Wear Plate should have a square edge and be free of dents or gouges.
Adjusting the Knife to Wear Plate Gap Tools Needed: • • 1. 7/16" wrench Gap Gauge (provided with Chipper) To adjust the Wear Plate Gap, loosen the three Nuts on the Carriage Bolts with a 7/16" wrench just enough so the Wear Plate will move but still have a slight resistance. Now you can slide the Wear Plate up or down (in or out) to achieve the correct gap setting (Figure 40).
Top Edge Short Side Beveled Edge New Knife Top Edge Short Side Beveled Edge Sharpened Knife Figure 43 • Take the Chipper Knife to a machine shop for proper sharpening. • How many times a Knife can be sharpened is determined by how much material needs to be taken off to sharpen or to compensate for dents or gouges. • A new Chipper Knife has 1.579" measurement between the short side bevel edge and the Knife Top Edge (Figure 43 “New Knife”).
Removing and Replacing the Wheels The Wheels on the DR 16.50 FTP PRO Rapid Feed Chipper are pneumatic and have pressed in Bearings for easy transport. With use, tires or Bearings may need replacing. The following procedures will explain the replacement procedures. SHUT DOWN THE ENGINE, WAIT FOR ALL MOVING PARTS TO COME TO A COMPLETE STOP, REMOVE SPARK PLUG WIRE, DISCONNECT THE NEGATIVE BATTERY CABLE, THEN WAIT 5 MINUTES BEFORE PERFORMING ANY MAINTENANCE PROCEDURE OR INSPECTION ON THE CHIPPER.
The Clutch obtains its power from the Engine RPM. The lower the engagement speed, and the higher the maintained Engine speed, the more torque the Clutch can transfer to the driven unit. NEVER operate the DR RAPID-FEED CHIPPER Engine at less than full RPM when chipping. NOTE: At engine start-up, the engine of your chipper operates under no load until approximately 1800 RPM, at which speed the centrifugal clutch engages and begins driving the rotor. Proper engine speed for chipping is 3400-RPM +/- 200 RPM.
Tools and Supplies Needed: • • 1. Key Keyway 9/16" Wrench Anti-seize compound Remove the Belt Guard and Belt (see “Removing and Replacing the Drive Belt” in this Chapter). 2. With a 9/16" wrench, remove the Clutch Bolt, Lock Washer and Washer and then slide the Clutch from the Crankshaft (figure 46). 3. Remove the Key from the keyway in the Engine Crankshaft and set it aside. 4. Clean the engine crankshaft and remove any burrs, then apply Anti-seize compound to the Crankshaft. 5.
To connect a battery charger to your DR RAPID-FEED CHIPPER, follow the steps listed below. 1. Attach the black (-) battery charger wire to the battery negative (-) terminal, and attach the red (+) battery charger wire to the battery positive (+) terminal. 2. Plug the battery charger into an outlet. WHEN YOU ARE FINISHED CHARGING THE BATTERY, DISCONNECT THE CHARGER FROM THE OUTLET FIRST, THEN DISCONNECT THE BATTERY CHARGER WIRES FROM THE BATTERY.
End of Season and Storage • SHUT DOWN THE ENGINE, WAIT FOR ALL MOVING PARTS TO COME TO A COMPLETE STOP, REMOVE SPARK PLUG WIRE, DISCONNECT THE NEGATIVE BATTERY CABLE, THEN WAIT 5 MINUTES BEFORE PERFORMING ANY MAINTENANCE PROCEDURE OR INSPECTION ON THE CHIPPER. • NEVER STORE THE DR RAPID-FEED CHIPPER WITH FUEL IN THE FUEL TANK INSIDE A BUILDING WHERE IGNITION SOURCES ARE PRESENT, SUCH AS HOT WATER AND SPACE HEATERS, CLOTHES DRYERS AND THE LIKE. IF YOU ARE GOING TO DRAIN THE FUEL TANK, DO THIS OUTDOORS.
