– Slacken: loosen adjusting sleeve (6) and screw nut (7) against it. • For coupling cables with load- removal spring (8): Before making an adjustment the spring must be unhooked and afterwards hooked on again. The coupling cable is correctly adjusted when the spring expands 2 to 3 cm when coupling takes place. – Tighten: Screw lock-nut (9) upwards. – Slacken: Screw lock-nut (9) downwards. Checking the drive system (STH 5.56, STH 8.66, STH 10.66 C) Figure 13 Caution Risk of damage to the machine Take care when tipping the machine to see that – the machine stays balanced and – no fuel or oil runs into the air filter or out of the machine. • Loosen screws to frame cover; if necessary tip the machine forwards. • With the coupling lever for the drive system released (Figure 1, item 2) change into all gears; in doing so the friction wheel (2) should not come into contact with the drive wheel (3). If it does, slacken the coupling cable (see “Making adjustments to the coupling cable”). • In each gear, press the coupling lever for the drive system; the friction wheel must make contact with the drive wheel. If it does not, tighten the coupling cable (see “Making adjustments to the coupling cable”). • As required clean the drive wheel and the rubber on the friction wheel; they must be free of grease. • If necessary remove ice on parts which are iced over. Tightening the V-belt (STH 953) Figure 5 If the worm is running irregularly at the constant engine speed, the tension of the V-belt (5) must be adjusted. • If there is an additional hole (3b) on the coupling lever (1), hook the coupling cable (2) into the higher hole (3b). English Operating Manual – Snowthrower • If there is no additional (higher) hole or it is already in use, then – Remove the V-belt cover (4). – Hook spring (6) at the end of the coupling cable into the next highest hole (from 7a to 7b, from 7b to 7c). – Replace V-belt cover. Adjusting the shift lever (STH 8.66, STH 10.66 C) Figure 12 • Remove spring clip (4) and washer (5), extract spindle nut (6) from the hole (7). • Press gearshift arm (2) downwards, set shift lever (3) to gear “6”. • Rotate spindle nut (6) in such a way that the pin can be put into the same hole (7). • Secure spindle nut with washer and spring clip. Adjusting the caterpillar track (STH 10.66 C) Figure 6 The caterpillar track (1) is correctly adjusted if it can be forced down by hand by 10–12 mm. If it can be forced down by a greater or lesser amount, it must be adjusted: • Set the machine on a secure and horizontal support so that the caterpillar tracks no longer touch the ground. • Rotate nut (2) until the caterpillar track has the correct tension: – To tighten, rotate in clockwise direction – To slacken, rotate in anti- clockwise direction. Replacing the caterpillar track (STH 10.66 C) Figure 6 • Set the machine on a secure and horizontal support so that the caterpillar tracks no longer touch the ground. • Rotate nut (2) sufficiently in an anti-clockwise direction to enable the caterpillar track to be removed. • Replace caterpillar track and adjust the tension of the new caterpillar track with the nut (2) (see “Adjusting the caterpillar track”). Replacing a shear bolt Figure 9 The worm (3) is fastened to the drive shaft (4) with shear bolts (1) and lock-nuts (2). The bolts are constructed in such a way that they break (shear off) if the worm strikes solid extraneous objects. In this way damage to the machine is prevented. These bolts (1) and nuts (2) may only be replaced with original spare parts (two replacement bolts and lock-nuts are supplied with the machine): • Remove sheared-off bolt and nut, clean place of attachment and lubricate it. • Use a new shear bolt and lock-nut to replace the broken one. Replacing the clearing plate (STH 5.56, STH 8.66, STH 10.66 C) Figure 7 • Remove screws (6), washers (7) and nuts (8). • Replace clearing plate (5). • Screw new clearing plate to housing with screws, washers and nuts. Replacing the clearing plate (STH 953) Figure 11 • Tip machine backwards. • Remove screws (4) and nuts (5). • Replace clearing plate (2). • Screw new clearing plate to housing with screws and nuts. • Tip machine back again, check setting (see “Adjust clearing plate”). Replace skids Figure 7 • Remove nuts (2), washers (3) and bolts (4). • Replace skids (1) on both sides of the housing. • Adjust new skids (see “Adjust the skids”). Preparing the machine for non-use ! Danger of causing an explosion by fuel fumes igniting Before you prepare the machine for non-use, empty the fuel tank into a suitable container in the open air (see “Engine instructions”). When the machine is not to be used for more than a month, e.g. after the winter: • Prepare engine (see “Engine instructions”). • Clean machine. • To protect from rust, wipe over all metal parts with an oily cloth or spray with spray lubricant. • Park the machine in a clean, dry enclosed space.
