Service Information Document Title: Function Group: Information Type: Date: Cab, removal 810 Service Information 2014/6/10 Profile: Cab, removal     Attach wire ropes to the lifting hooks of the cab, and lift the cab until there is no slack in the wire ropes. Remove the 7 mounting screws (2, 5, 6) located at the bottom plate of the cab. Disconnect the main wiring connectors, air duct and storage box. Lift the cab just a little, and after confirming safety all around, lift up and out. NOTE! Cab weight : about 275 kg (605 lbs)

Service Information Document Title: Function Group: Information Type: Date: Viscose mount, description 810 Service Information 2014/6/10 Profile: Viscose mount, description    The bottom plate where cab is assembled is mounted on 5 viscose mounts, and then assembled to the upper deck. Viscose mounts is designed to absorb vibration generated when operating the machine. Silicon oil and gas inside the viscose mounts absorbs extreme shock impact. CAUTION If the viscose mount is dropped or impacted, silicon oil may leaked and lower the performance. CAUTION The exterior of viscose mount is natural rubber with low oil resistance. Avoid contact with grease and oil.

Service Information Document Title: Function Group: Information Type: Date: Viscose mount, installation 810 Service Information 2014/6/10 Profile: Viscose mount, installation 1. 2. 3. 4. Install the viscose mount on upper deck by tightening screw (8). Tightening torque : 6.5 ± 0.7 kgf·m (47 ± 5 lbf·ft) Check for deformation and debris on mounting surface. CAUTION The difference of height for viscose mount installed (5pcs) must be within 1mm. Tighten the lock nut (6) with specified torque. Tightening torque : 26.7 ± 2.7 kgf·m (193 ± 19 lbf·ft) Cover the floor mat. NOTE! If the ambient temperature is less than 0°C, the viscosity of silicon oil inside the viscose mount is high, and the ride is some what rough. After operating a few minutes, the viscosity will be lowered by heating due to vibration and the ride will be much smoother.

Remove floor mat (2), and remove the bottom plate by loosening nut (6) tightened to bottom plate (1). Remove the viscose mount by loosening screw tightened to upper deck.

Service Information Document Title: Function Group: Information Type: Date: Air conditioning unit, description 870 Service Information 2014/6/10 Profile: Air conditioning unit, description The advanced integrated air conditioning system with the heating and the cooling system installed in a single unit is designed to provide a comfortable indoor environment in all seasons. The integrated system is ergonomically designed for the most efficient air flow distribution. The easy to use control panel provides a selection of cooling/heating and indoor/outdoor air through 8 levels and 4 fan speeds. Characteristics of an integrated air conditioning system     This system provides a comfortable indoor environment with powerful cooling and heating capacity in all weather conditions. The thermistor installed in the integrated air conditioner protects the evaporator and cooling system from freezing. The cooling and heating system can be operated simultaneously to control humidity and indoor temperature. According to the indoor and outdoor air condition, indoor or outdoor air circulation can be selected. All fresh air is drawn through the air filter installed between the duct and the cab vent.
