OPERATION

Pre-start-up inspection
The following Pre-start-up inspection must be performed before the start of each work session or after every four hours of use, whichever is first.. If any fault is discovered, the compactor must not be used until the fault is rectified.
Thoroughly inspect the compactor for signs of damage. Check components are present and secure. Pay special attention to the belt drive safety guard fitted between the engine and the vibrator unit.
2. Check the engine oil level and top up as necessary.
3. Check the engine fuel level and top up as necessary.
4. Check for fuel and oil leaks

Start and stop Procedure
Diesel Engine

1. Open the fuel cock.
2. Turn the governor lever to “STARTING” position.
3. Hold the recoil starter handle.
4. Pull the starter handle until you feel the resistance, then return handle slowly.
5. Press the decompression lever to “Non-compression” position. The lever will return back automatically after the engine started.
6. Hold the recoil starter handle with two hands and pull it hardly.
7. It is difficult to start the engine at cold weather. Remove the rubber plug on the cylinder head and fill about 2CC engine oil before starting.
8. To stop the engine, set the governor lever to the low speed position, then run the engine at zero load five minutes.
9. Set the governor lever to the “STOP” position. Do not stop the engine with the decompression lever.
10. Set the fuel cock the “OFF” position.
11. Pull the recoil starter handles slowly, until you feel resistance. (At this point, the decompression just begins and intake/exhaust valves are both closed, thus the cylinder can be prevented from rust.

Petrol Engine

1. Open the fuel tap by moving the fuel ON/OFF lever fully to the right.

2. If starting the engine from cold, set the choke ON by moving the choke lever fully to the left. If restarting a warm engine, the choke is usually not required. However, if the engine has cooled to a degree, partial choke may be required.

3. Turn the engine ON/OFF switch clockwise to the “1” position.

4. Set the throttle to the idle position by moving the throttle lever fully to the right.
   Do not start the engine on full throttle, as the compactor will vibrate as soon as the engine starts.

5.  Taking a firm hold of the control handle with one hand, grasp the recoil starter

6. handle with the other. Pull the recoil starter until engine resistance is felt, then

7. let starter return.

8. Taking care not to pull the starter’s cope fully out, pull the starter handle briskly.

9. Repeat until the engine fires.

10.  Once the engine fires gradually, set the choke lever to the OFF position by

11. moving it to the right.

12. If the engine fails to fire after several attempts, follow the trouble-shooting guide on page 9.

13. To stop the engine, set the throttle to idle and turn the engine ON /OFF switch anticlockwise to the “0” position.

14. Turn the fuel off.

The machine is best suited to the compaction of bituminous and granular materials e.g. granular soils such as silt and clay are best compacted using the impact force produced by a vibrating rammer.
Where possible the site should be graded and leveled before commencing compaction.
Correct moisture content in soil is vital to proper compaction. Water acts as a lubricant to help slide soil particles together.
Too little moisture means inadequate compaction; too much moisture leaves water-filled voids that weaken the soil’s load-bearing ability.
Compaction of dry materials will be facilitated by moistening with a water hose fitted with a sprinkler.
Excessive watering or water content will cause the machine to stall.
The optional water tank kit is recommended when the machine is used on bituminous surfaces as the water film prevents a build up of material on the underside of the plate.
Use unleaded grade petrol and ensure that the fuel is free from contamination.
The vibratory motion provides a self propelling action. Position the handle at the opposite end of the machine to the vibrator.
For more information on starting and correct operating procedures of the motor, refer to the motor operation manual supplied with the unit.
Increase the motor speed to the maximum setting using the hand throttle lever, before commencing compacting.
The machine should be controlled by grasping the handle with both hands and applying restraint to control the forward motion.
Steer the machine by moving the handle sideways to the right or left.
ALWAYS maintain good footing so that you do not slip and loose control when starting or operating the machine.
If the optional water tank is fitted, the flow rate can be controlled by adjusting the cock in the supply hose to sprinkler bar.
Inspect the water hose and its connections to ensure that they do not leak.

CARE AND PREVENTIVE MAINTENANCE

Check the oil level in the motor crankcase daily.
Inspect the rubber anti vibration mounts for wear or deterioration.
If the optional water tank is fitted inspect the water hose and its connections to ensure that they do not leak.
Clean the underside of the plate regularly to prevent a build up of material.
CAUTION:  Inspection and other services should always be carried out on hard and level ground with the engine shutdown.
Inspection and Maintenance Service Tables.
To make sure your plate compactor is always in good working condition before using, carry out the maintenance inspection in accordance with Tables 1 through 3.
TABLE 1. MACHINE INSPECTION

TABLE 2. ENGINE CHECK

(For details, see separate engine Manual)

Item| Hours of Operation
Leakage of oil fuel| Every 8 hours (every day)
Tightness of fastening Threads| Every 8 hours (every day)
Engine oil check and replenishment| Every 8 hours (every day) (Replenish to specified Max. level)

TABLE 3. TIGHTENING TORQUE (in. kg/cm) Diameter

*(In case counter-part is of aluminium)
(Threads in use with this machine are all right handed)
Material and quality of material is marked on each bolt, and screw.

CAUTION: These inspection intervals are for operation under normal conditions. Adjust your inspection intervals based on the number hours plate compactor is in use, and particular working conditions.
CAUTION:  Fuel piping and connections should be replaced every 2 years.
Daily Service

• Check for leakage of fuel or oil.
• Remove soil and clean the bottom of compaction plate.
•  Check engine oil.
• Check for loose screws including tightness. See Table 3 above (tightening torque), for retighten

Changing Vibrator Oil / Vibrator Grease
When changing the vibrator oil, remove the drain plug located at the bottom- right of the vibrator, and simply tip the compactor to drain the oil. Note that the oil will drain more easily while it is hot. For MS50 series, MS60 series, MS80
series, MS90 series, replace the oil with 200ML of 10W-30 motor oil; For MS100 series, check and regrease exciter every 500 hours of operation, use SHELL ALVANIA R3 grease or equivalent.

Air Filter

1. The air filter element should be cleaned because a clogged air cleaner can cause poor engine starting, lack of power and shorten engine life substantially.
2. To clean or replace air filter loosen the wing nut on the air filter housing (Figure 1), remove the cover and take out air filter cartridge. If only cleaning of the air filter is desired blow through the air filter cartridge from the inside, moving a jet of dry compressed air up and down until all dust is removed.

CAUTION:
NEVER attempt to check the V-belt with the engine running. Severe injury can occur if your hand gets caught between the V-belt and the clutch. Always use safety gloves.

• Checking and Replacing the V-belt and Clutch

After 200 hours of operation, remove the upper belt cover to check the V-belt tension (Figure 2). Tension is proper if the belt bends about 10mm when depressed strongly with finger between shafts. Loose or worn V-belts reduces power transmission efficiency, causing weak compaction and reduces the life of the belt itself.

CAUTION:  Whenever the compactor’s vibration becomes weak or lost during normal operation regardless of operation hours, check the V-belt and clutch immediately.

• Replacing the V-belt
  Remove the upper and lower belt covers. Engage an offset wrench (13mm) or the like to vibrator pulley (lower) fastening bolt. Engage waste cloth or the like at midway of V-belt on the left side and while pulling it back strongly, rotate the offset wrench clockwise so that the V-belt will come off.

• Reinstalling the V-belt

• Engage V-belt to lower vibrator pulley and push the V-belt to left side of upper clutch and, in the same manner as in removal, rotate offset wrench clockwise so that the V-belt goes back on.

• Checking Clutch

Check the clutch simultaneously with V-belt checking. With belt removed, check outer drum of the clutch for seizure and “V” groove for wear or damage with your eyes. Clean the “V” groove as necessary. Wear of lining or shoe should be checked with running check. If the shoe is worn, power transmission becomes deficient and slipping will result.
