CRT 36 Operation Control locations and functions: Ref. Description Ref.
Operation 3.2 CRT 36 Position of the Operator Safe and efficient use of this machine is the operator’s responsibility. Full control of the machine is not possible unless the operator maintains the proper working position at all times. While operating this machine the operator must: 3.
CRT 36 3.4 Operation Break-in Period See Graphic: wc_gr001252 3.4.1 To break in the gearboxes, run the engine at 50% of full throttle for the first 2–4 hours. This will prevent premature wear and extend gear life. NOTICE: Running the engine at full throttle during the break-in period could result in premature gear failure. 3.4.2 3.5 Verify that the horizontal blade pitch links are properly assembled.
Operation 3.6 CRT 36 Starting Before starting the operator must know the location and function of all controls. 3.6.1 Push down on the throttle foot pedal, turn the engine keyswitch (o), and hold it until the engine starts. Note: If the engine is cold, pull out the choke control knob fully. The choke may need to be opened even when starting a warm engine. NOTICE: Cranking the engine for more than 5 seconds can cause starter damage.
CRT 36 3.8 Operation Operation To utilize your Wacker Neuson Ride-On Trowel to its fullest capacity, the machine should be driven in the direction that the operator is facing. This will finish the widest possible area, while giving the operator an excellent view of the slab surface about to be troweled. When the machine reaches the end of the slab, make a 180° U-turn, and repeat the straight line of direction to the other end of the slab.
Operation 3.9 CRT 36 Steering See Graphic: wc_gr000146 Refer to the illustration for the necessary hand motions to move the trowel in the desired direction, described below. 1 - forward 2 - reverse 3 - rotate clockwise 4 - rotate counter-clockwise 5 - left sideways 6 - right sideways 1 2 3 4 5 6 wc_gr000146 28 wc_tx000639gb.
CRT 36 Operation 3.10 Pitch Adjustment When changing or setting the pitch (angle) of the trowel blades, slow the machine, set the desired pitch on the left side of the machine, then adjust the right side to match. To increase pitch: Rotate the left pitch control (L) clockwise, rotate the right pitch control (R) counterclockwise. To decrease pitch: Rotate the left pitch control (L) counterclockwise, rotate the right pitch control (R) clockwise. Working Conditions of Concrete Suggested Working Pitch 1.
Maintenance 4 CRT 36-24A/25 Maintenance 4.1 Periodic Maintenance Schedule The table below lists basic machine maintenance. Tasks designated with check marks may be performed by the operator.

CRT 36-24A/25 4.4 Maintenance Control Arm Adjustment (Forward or Backward) See Graphic: wc_gr003732 The control arms should line up evenly. If arms appear out of adjustment, they can be re-adjusted forward or backward as follows: 4.4.1 Loosen jam nuts (b). 4.4.2 Turn the vertical linkage (a) as follows: 4.4.3 • Extend the linkage to adjust control levers forward. See section 4.5 before extending linkage. • Shorten the linkage to adjust control levers backward.
Maintenance 4.5 CRT 36-24A/25 Right-hand Control Arm Adjustment (Right or Left) See Graphic: wc_gr003732 The arms should be set to be perfectly vertical. Should the arms come out of adjustment, adjust as follows: 4.6 4.5.1 Loosen the jam nuts (d). 4.5.2 Drop the horizontal linkage (e) down to clear the bracket. 4.5.3 Shorten the linkage to move the control arms to the left. 4.5.4 Extend the linkage to move the control arms to the right. 4.5.
CRT 36-24A/25 4.7 Maintenance Transporting Trowels See Graphic: wc_gr003733 ALWAYS turn the engine off and remove the key from the machine before moving or transporting machine. WARNING To hoist the trowel: Attach a sling or chains through the lifting bars (a) on each side of the seat pedestal. NOTICE: Make sure the lifting device has enough weight-bearing capacity to lift machine safely. Refer to section Technical Data.
Maintenance 4.8 CRT 36-24A/25 Drive Belt See Graphic: wc_gr003734 To replace the drive belt: 4.8.1 Place the trowel on a flat, level surface with the blades pitched flat. 4.8.2 Turn engine off and disconnect battery. 4.8.3 Remove the beltguard. 4.8.4 Remove 2 bolts (a), washers (b) and nuts (c) from each bearing flange. 4.8.5 Remove the 4 bolts (d) holding each inside universal joint to the shaft fitting. Remove universal joints and shims (if included) from ends of drive shaft. 4.8.
CRT 36-24A/25 4.9 Maintenance Battery Jump Start Procedure Occasionally, it may be necessary to jump start a weak battery. If jump starting is necessary, the following procedure is recommended to prevent starter damage, battery damage, and personal injuries. DANGER Jump starting a battery incorrectly can cause battery to explode, resulting in severe personal injury or death. Do not smoke or allow ignition sources near the battery, and do not jump start a frozen battery.
Maintenance CRT 36-24A/25 4.10 Spark Plug Clean or replace spark plug as needed to ensure proper operation. Refer to the engine Owner’s Manual. Note: Refer to the Technical Data for the recommended spark plug type and the electrode gap setting.
