(1) Compression tester (2) Glow plug adapter
1. Turn off the engine after it has warmed up and remove the air filter, the muffler, the venting pipe, the glow plug line and glow plugs. 2. Mount a compression tester (1) (Part No. : 07000-30208) glow plug adapter (2) (for the diesel engines V2607 or V3007 / V3307) at the glow plug hole. 3. After making sure that the speed control lever is in the stop position (no injection), turn the engine with the starter motor at 200 to 300 min1 (rpm). 4. Read off the maximum pressures and measure more than twice.
■ NOTE
• Check compression pressure with properly adjusted valve clearance • Always use a fully charged battery for the compression pressure check. • The deviation between the individual values may not be more than 10%.

Engine Adjusting valve clearance
■ IMPORTANT ■ The valve clearance must be checked and adjusted when the engine is cold. 1. Remove the high-pressure pipe, the glow plug lines, the glow plugs and the valve cover. 2. Align the OT marking 1TC on the flywheel in the timing wheel at the top of the flywheel housing so that the first piston (front cover side) is at the compression top dead centre point. 3. Loosen the lock nut (4) of setscrew (3) : (push rod side) and push the feeler gauge between the rocker arm and the head of the rocker arm bridge. Adjust the setscrew (3) to the specified value and then tighten the lock nut. Valve clearance A Factory specification 0.13 to 0.17 mm

Engine Checking oil pressure
1. Remove the engine oil pressure switch and install a measuring adapter (Part No. 07916-32032). 2. Start the engine. After the operating temperature has been reached measure the oil pressure at idling speed and at nominal speed. 3. If the oil pressure is below the permissible limit value, the following causes are possible: •Oil level too low •Oil pump defective •Oil screen clogged •Oil filter cartridge clogged •Oil gallery clogged •Excessively large oil gap crankshaft bearings •Foreign body in the overpressure valve (During assembly) - After the engine oil pressure has been checked, retighten the engine oil pressure switch at the specified torque.

Engine Checking coolant thermostat
1. Press the thermostat valve down and clamp a thread between valve and valve seat. 2. Place the thermostat and a thermometer in a container with water and gradually heat up the water. 3. Hold the thermostat suspended from the thread in the water. When the water temperature rises, the thermostat will open and fall off the thread. Measure the temperature at this moment with the thermometer. 4. Further heat the water and read the temperature when the valve has opened by approx. 8 mm. 5. If the measured value is not within factory specifications, replace the thermostat.

Engine Adjusting start of pumping
1. Ensure that the injection time markings (1) on the injector pump and on the flywheel housing agree, as shown in the figure. 2. Remove the injection lines. 3. Remove shutdown solenoid. 4. Slowly turn the flywheel counter-clockwise (as viewed onto the flywheel), until the fuel reaches up to the opening of the pressure valve holder (3) for the first cylinder. 5. Once the fuel reaches as far as the opening of the pressure valve holder (3) of the first cylinder, turn the flywheel back clockwise by 1.6 rad (90°). 6. Now turn the flywheel counter-clockwise up to about 0.17 rad (10°) before TDC. 7. Continue turning the flywheel slowly counter-clockwise and only stop turning when fuel begins to rise, in order to determine current start of pumping. 8. Check the number of degrees on the flywheel. The flywheel has the markings "1TC" for the crank angle before top dead centre (TDC) of piston 1. 9. If the start of pumping is not within specification, turn the injector pump to adjust the start of pumping.

■ NOTE
• Take care that rotating parts are no touched during the test. Maintain a safety margin from rotating parts.
(Before testing) • Before testing the generator, check the battery terminals, circuit connections, fan belt tension, charge indicator lamp, as well as the fuses in the circuit. • Use a charged battery for the test.

Functions of the front lift
Function Operation Symptom Example Photograph/symbol/ remark
1. Lifting/lowering Joystick forwards/backwards
Lift and front unit raises and lower themselves proportionally to the joystick movement and correspondingly fast raised unit automatically pressed horizontal at the top selected floating position is deactivated.
Raising or lowering of a front implement, e.g., hedge clippers
2. Lifting Pull joystick back
Lift raises itself Hydro reservoir fills itself time-offset
Front implement spontaneously rises without delay, important, e.g., when facing obstacles while ploughing snow
3. Driving with raised implement
No operation necessary
Hydro reservoir damps vibrations Driving mode Implement acts as a damping mass on the vehicle
Suspension properties with implement better than without
4. Single-acting setting
Toggle switch under arm rest
EW: Implement cannot be actively pressed, can passively evade upwards
EW: Mower cannot be loaded by the machine.
5. Double-acting setting
Toggle switch under arm rest
DW: active operation in both directions
DW: Snow plough can be pressed downwards
6. Floating position Button on joystick
Lift and front implement freely movable vertically Is deactivated while lifting Indicator lamp on operating console
Necessary if ground adaptation of the implement is desired

Functions of the front lift
7. Transverse inclination "OFF“
Shut-off switch under arm rest
Transverse direction of the front lift (in the longitudinal axis) is preserved (lifter transversely rigid)
Moving on inclines Cutting through hard snow
8. Transverse inclination "ON“
Mode switch under arm rest
Lift freely movable transversely (floats)
Implement is intended to adapt to the ground in connection with implement relief
9. Transverse inclination „AUTO“
Mode switch under arm rest
Lift is freely movable as soon as floating position for "lowering" is activated Is automatically deactivated when lifting
Optimal for many devices: floating position vertically and transversely automatic for optimal adaptation to the ground and easy operation
10. Active transverse
inclination adjustment (option)
Toggle switch on operating console or joystick
Lift is actively adjusted transversely Speed adjustable via potentiometer Mode switch "Transverse" to "Off"
Snow cutter can be actively adjusted transversely to produce a horizontal base
11. Active lateral adjustment (option)
Toggle switch on operating console or joystick
Lift is actively adjusted laterally (about vertical axis)
Implement can be displaced somewhat laterally or steered in the curve
12. Hydraulic implement relief (option)
Switch on operating console Pressure setting on B-pillar at right Floating position "Off" must be "On"
Front implement is "carried" with set pressure in the front left, so that it lies with less weight on the ground. Amount of relief adjustable via pressure gauge Indicator lamp on operating console Is deactivated when lifting
Mower: easier guidance of the implement, better traction and steering ability of the vehicle Snow plough see above
