1. Remove the Belt Cover using a 7/16" Socket with a 6" Extension to remove the four (4) 1/4" Cover Bolts
(Figure 19 on page 33).
2. Pull the machine backward and squeeze the Drive Clutch Lever until it stops freewheeling. At this point,
the Drive Clutch Lever should be about 4" from the tip of the Lever to the Handlebar (Figure 21a).
3. Measure the amount of Clutch Spring stretch (Figure 21b). The Clutch Spring should measure 1-1/8"
when engaged.
Tip: Either tie the Drive Clutch Lever to the Handlebar or have someone hold it for you during the
measurement.
4. Using two (2) 1/2" Wrenches, loosen the Lock Nut and then tighten or loosen the Cable Adjuster Nut in
front of the Drive Clutch Lever (Figure 21a) until you obtain the 4" distance as noted in step 2.
5. Holding the Adjuster Nut in place with one Wrench, tighten Cable Lock Nut firmly with the other
(Figure 21a).
6. Release the Drive Clutch Lever and then move it to the Handlebar again and hold it. Check the Clutch
Spring length to assure it stayed in adjustment.
7. Readjust as required.
8. Reinstall the Belt Cover and reconnect the Spark Plug Wire.
9. Test run the DR WALK-BEHIND LEAF & LAWN VACUUM to insure proper operation after this or any
other maintenance procedure.
