6 Dis-assembly of Hedgeclipper Place on service tooling

7 Leave front handle assembled Do not undo these screws unless to repair front handle A. Remove all screws from rear handle and remove upper handle clamshell. B. Leave front handle assembled is not needing repair

8 C. Remove from lower handle the rear triggers, Bowden cables, front handle sub assembly and slider mechanism. D. Disconnect motor leads from terminal block and lift the main clamshell body and blades from the lower rear handle. Main clamshell body and blades E. Remove all clamshell screws and remove upper clamshell. Re-assembly of Hedgeclipper F. Refit upper clamshell ensuring spirol pins are located, latch is located and no wires are nipped.

9 G. Replace screws and tighten to 15/1.7Nm. H. Lift main clamshell body and blades, and locate into lower rear clamshell. I. Reconnect motor leads to terminal block. J. Place yoke inside of Slider and push Timing Pin ( ) through hole in the side of the slider through the hole in the pinion and out of the hole in the other side of the slider. The three parts are now held together by the pin, however, the yoke should be free to move.

10

11 K. Hold the slider and yoke so that when looking at the parts they are in the same orientation as the sketch above. Pull the yoke away from the slider until it is tight against the pinion. Hold in this position with the left hand. L. Pick up rack and orientate with respect to yoke and slider as the sketch above. Locate the bottom end of the Timing Pin through the hole in the side of the rack. Slide rack up the timing pin until it gets to the slider. Pull the Timing Pin down until the rack can move across the side of the slider and all the holes line up. Push the timing pin back through the holes. All the pieces of the switching mechanism are now held together by the Pin but the yoke should be able to move in and out of the slider.

12 All the pieces of the switching mechanism are now held together by the Pin but the yoke should be able to move in and out of the slider.

13 M. Offer up the switch mechanism to the lower handle with the shaft of the rack positioned into the left-hand side hole of the main clamshell body. The trick is to slightly lift the main clamshell whilst locating the switch mechanism into the handle. Push the Timing Pin down through the hole in the lower handle clamshell. The switch mechanism is now positioned correctly. N. Working away from the switch mechanism towards the blades locate the spring against the first rib (ensure spring is correctly fitted on yoke boss) and the conduit fitting on the end of the Bowden cable is against the second rib. Finally, locate front handle into rear handle. O. Working away from the switch mechanism towards the cable locate the spring against the first rib (ensure spring is correctly fitted on slider boss) and the conduit fitting on the end of the Bowden cable against the other side. Dress the Bowden cable around the screw bosses and locate the two triggers into the pivot holes at either side of the lower rear handle. P. Place the upper rear handle over your right arm and hold the triggers in place with the fingers of the right hand. Maneuver the upper handle into the correct orientation and position onto the lower handle. Fit the two screws either side of the pivot point to 0.8/1.0Nm and then fit the screw at the cord protector ensuring the cord protector and triggers are correctly located. Q. Fit and tighten all other screws to 0.8/1.0Nm ensuring that the two screws at the very front of the rear handle are the two slightly longer ones. R. Pull Timing Pin from the hole in the lower handle clamshell. Check operation of switch mechanism by operating, with the handle locked into one of the two operating positions, the front and one of the rear triggers. Two clicks should be heard on operating the triggers and releasing them.

14 Pull timing pin ( ) out through lower clamshell Replacing sub assembly Blade and Gear.

15 1. Carry out steps A to D. Spirol pins 2. At this point the Spirol Pins will be still through the blade support into the lower handle or may have pulled out of the lower clamshell, being held firmly by the cover clamshell. With a pair of pliers remove the pins. 3. Take hold of the blade with one hand and rotate the blade tip upward to approximately a 45-degree angle and then lift the blade and gear from the clamshell. 4. Ensure correct location of motor and intershaft. 5. Fit sintered bearings to the gear shaft and present the blade gear assembly to the clamshell with the tip held up at 45 degrees. 6. Position the gear and shaft into the clamshell ensuring correct tooth alignment and then lower the tip of the blade down until the blade support rests in the clamshell. 7. Align the two holes in the blade support with the corresponding holes in the clamshell and push the spirol pins through and into the clamshell until approx. 8mm of spirol

16 pin is left above the top of the blade support. Note light encouragement with a soft hammer may be required to locate the spirol pins. 8. Grease the gears as required. 9. Carry out steps E to Q.
