1 Tonne D C F E A B Towing the vehicle In order to tow the vehicle, the hydrostatic drive on the engine must be bypassed, and the spring-applied brakes at the two rear wheel motors must be disconnected. Bypassing the hydrostatic drive This is achieved by unscrewing two valves on the pump. One valve is beneath the footplate (Fig. 1 (A)); the other is opposite this, underneath the pump (Fig. 1 (B)). To activate the hydrostatic transmission bypass: • release lock nut (Fig. 2(C)); • screw in grub screw (Fig. 2(D))) until flush with top of nut (C); • tighten nut (D). To re-activate the hydrostatic transmission: • screw back item D to stop; • screw back the nut and tighten. Disconnect the spring-loaded brakes • Dismantle the two extractors (Fig. 3 (E))) attached at the rear axle box (This is achieved by unscrewing the hexagon bolts) • remove the plastic plug in the centre of the wheel motor face. • place the extractor on the wheel motor (Fig. 4 (F))) and screw in the hexagon bolt removed earlier. • Tighten bolt to 42 Nm until wheel removes freely. • Replace extractors to re-activate spring-loaded brakes. CAUTION Chock the wheels when the brakes are disconnected. When towing the vehicle: • Do not exceed the maximum towing speed of 2 km/h. • Do not exceed the towing distance of 1 km. • Under no circumstances drive the vehicle with the brakes disconnected.
