Service Information Document Title: Function Group: Information Type: Date: Coolant with freezing and corrosion protection 030 Service Information 2014/6/13 Profile: ART, A40D [GB] Coolant with freezing and corrosion protection Anti-freeze Check the anti-freeze every 500 hours. At delivery, the cooling system is filled with a mixture of 50% water and 50% Volvo Construction Equipment concentrated coolant with freezing protection down to -25°C. If there's a risk that the ambient temperature drops below this temperature, the freezing protection should be adjusted, see below. Corrosion protection Volvo Construction Equipment concentrated coolant contains active corrosion protection additives to protect engine and radiator. These additives have a limited service life. Therefore, change the coolant every 3000 hours. NOTE! Volvo Construction Equipment concentrated coolant may not be mixed with other brands of coolant or additives. Mixing could have negative effects. Volume and change volume cooling system; see Engine, capacities. The content of concentrated coolant with anti-freeze protection may not be below 40%. 40% provides protection against freezing down to -25° C. 50% provides protection against freezing down to -37° C.

Service Information Document Title: Function Group: Information Type: Date: Recovering and towing 050 Service Information 2014/6/13 Profile: ART, A40D [GB] Recovering and towing WARNING Before starting any recovery or towing work, make sure that the parking brake is applied and the wheels are blocked to prevent the machine from rolling. Extreme caution must be observed in connection with towing to prevent accidents and personal injuries. WARNING If the engine cannot be started, the brake and steering functions will be severely limited. In such cases, towing should only be performed in an emergency situation by experienced and trained personnel and only for the shortest possible distance (see towing). If possible, transport the machine on a trailer. General If possible, the engine should be running while recovering/towing the machine to ensure satisfactory braking and steering performance. Recovering Use a towbar, heavy-gauge cable or chain connected to the towing eyes at the front or rear of the machine to tow the machine to a suitable place or passable road. Towing      If the machine has to be towed to a workshop after recovery, use a towbar or heavy-gauge towing cable connected to the front towing eyes. A towbar must always be used if the machine that is to be towed has no brake function. The towing vehicle or machine must always be at least as heavy as the towed machine and have sufficient engine and braking power to tow and brake both machines on uphill and downhill grades. Always tow the shortest possible distance. Maximum towing speed under all conditions is 10 km/h. NOTE! The engine cannot be started by towing the vehicle. Case 1 (with engine running) The gearshift selector should be in neutral and the parking brake in the operating position. The machine can be towed for 10 km without taking special action. Case 2 (without engine running) Since the transmission is not lubricated when the engine is not running, the propeller shaft between the transmission and dropbox shall be removed. Then lubrication to the dropbox is maintained at the same time as the machine can be steered. Removing the propeller shaft 1. 2. 3. Place the machine in service position. Block the wheels so that the machine cannot start to roll and release all brakes. Make sure that the front or rear wheels are slightly raised off the ground before removing the propeller shaft's bolts. Filling compressed air system

If necessary, the compressed air system can be filled through the filler valve on the front part of the load unit frame by using compressed air from another machine. Releasing the parking brake When filling through the filler valve on the compressed air tank, the parking brake is released. The required minimum pressure is approx. 470 kPa (4.7 bar). The parking brake control must be in the operating position, that is, not applied. After recovering/towing The following safety measures should be taken before removing the towbar, heavy-gauge cable or chain after recovering/ towing: 1. 2. 3. Park the machine on a level surface. Apply the parking brake. Block the wheels to prevent the machine from rolling.
