Operation Using the Hedge Trimmer Preparations Use lopping shears to cut out thick branches first. Cutting Sequence If a radial cut is necessary, cut a little at a time in several passes. Cutting Techniques Vertical Cut: Swing the blade up and down in an arc as you move along the hedge. Use both sides of the cutting blade. Cut without standing directly next to the hedge, e.g. with a flower bed between operator and hedge.

Check cooling air intake area at base of crankcase. Remove all debris. Dirt build-up in these areas can lead to engine overheating, fire, or premature wear.
Maintenance (continued) Gearcase lubrication ■■Lubricate the cutter assembly gearcase by pumping one or two strokes of lithium-base grease into the grease fitting (A) using a levertype grease gun. CAUTION! Over lubricating can cause the gearcase to operate sluggishly and can cause grease to leak out.
Maintenance (continued) CAUTION! Do not remove the D-shaped shim washer from the gearcase clamp! The shim washer prevents damage from overtightening the tube clamp bolt. 3. Slide the gearcase out of the tube. Using a grease gun, pump lithiumbase grease (about 10 grams) into the grease fitting (B) on the gearcase until you see old grease being purged from the gearcase. Purged grease will be visible in the outer tube cavity. B Lubricate cutter assembly and gearcase Gearcase grease fitting 4.
