Assembly

Some parts, such as the throttle control, have the necessary fasteners pre-assembled –these will

need to be removed during the assembly process. • Suitable tools (not supplied) are required for

assembly.

1. Take all parts out of the carton and place them on a firm, flat surface. Remove all packing materials.

2. Screw the handle stopper (1) to the hole in the tab (A) at the rear of the machine. Secure the stopper

using an M10 nut (2) and tighten firmly.

3. Insert the handle tube chock (3) through the hole in the tab (B) on the right-handle handle mount (C) at

the rear of the machine, and secure using the M8 bolt (4), flat washer (5) and spring washer (6).

4. Lower the ends of the handle assembly (7) (the handle ends contain vibration isolating rubbers) into the

handle mounts (D) at the rear of the machine. Insert the handle so it is "trapped" between the handle

stopper (1) and the handle tube chock (2).

5. Secure the handle using 2 M10x65 bolts (8) and lock nuts (9). Tighten firmly, but do not over-tighten and

bind the handle.

6. Attach the throttle control (10) to the upper section of the handle in a

comfortable position and secure it using the supplied fasteners. Use

BCX650 Plate Compactor

Plate Compactor Pad (Optional)

The plate compactor pad can be used for compacting concrete paving slabs and stones. It provides a slight

cushioning effect to the compactor that may assist in reducing scratching / cracking or chipping of pavers. To

attach it:

1. Place the machine on its side –ensure that there is no fuel in the tank before-hand.

2. Bring the plate compactor pad (1) up to the machine compactor plate (A) and align the mounting slots in

the pad with the holes in the plate.

3. Secure the pad to the base by placing a plate pad bracket (2) against the plate compactor pad, then

securing the bracket and pad to the machine compactor plate using 3 M10x30 bolts (3), flat washers (4)

and spring washers (5). Firmly tighten the bolts, then repeat for the other pad bracket.

Trolley Wheel (Optional)

The trolley wheel makes moving the machine easier when it is not being used. The design of the trolley also

allows the machine to be left stationary without it resting on the compactor plate. To attach it:

1. Remove the pre-assembled bolts from the trolley (1) end brackets (A).

2. Attach the trolley end brackets to the holes at the rear of the machine (B) using the previously removed

fasteners. Do not fully tighten the trolley fasteners –the trolley components must pivot freely. Over-

tightening may make using the trolley difficult.

Before Use Checklist

Ensure that you carry out all procedures below before starting the engine or operating the

equipment. All procedures described are generic in nature and slight variations between

different models may exist. Failure to follow the checklist and carry out the procedures

correctly may result in making the product warranty void. The product is NOT supplied with engine oil,

although traces of oil from the manufacturing process may be present. It is essential to add adequate engine

oil of the correct type to the engine before use –see Checking and Changing Engine Oil. Failure to add

engine oil will void the product warranty.

Engine Oil

Four-stroke engines require engine oil in the crankcase for lubrication of internal components. Severe or

irreparable damage may occur if the engine is allowed to run without engine oil. The engine oil level requires

regular maintenance. Check the engine oil level and ensure that the oil level is at or just under the maximum

level indicator.

Always check the engine oil level before starting the engine. See Checking and Changing Engine Oil.

Air Filter

The air filter is used to prevent dirt and other particles from possibly entering the engine and causing internal

damage to it. The air filter requires regular maintenance.

Always check the air filter before starting the engine. See Checking, Cleaning and Replacing the Air Filter.

Fuel

Petrol/fuel/gasoline is extremely flammable –keep clear of naked flames or other ignition

sources. • The engine must be cool before refuelling.

Adequately fill the fuel tank with the correct fuel type.

•Use non-ethanol unleaded petrol (higher RON values will provide best engine performance). Do not use

old or contaminated fuel.

To fill or top up fuel:

1. Place the machine in an upright position on a flat and level surface.

2. Clean the machine around the fuel filler so that no dirt or other material enters the engine when the cap

is removed.

3. Remove (rotate left) the fuel filler cap.

4. Using a funnel, carefully fill the tank with fuel. Do not fill above the top of the strainer (if equipped) or

otherwise overfill the tank.

5. When finished, reinstall (rotate right) the fuel filler cap until firm. Wipe away any residual fuel from the

machine. If fuel has been spilt, move the machine away from the spillage before starting the engine.

BCX650 Plate Compactor

Engine Starting and Compactor Operation

Starting the Engine

1. FUEL –Place the fuel tap (A) in the "ON" position.

2. CHOKE –If the engine is cold, place the choke (B) in the "COLD" position. If the engine is warm or the

ambient temperature is high, place the choke in the "RUN" position.

3. IGNITION –Place the engine ON/OFF switch (C) in the "ON" ("I") position.

4. Move the throttle lever (D) approximately 1/3 of the way toward the "FAST" position.

5. START –Slowly pull out the starter cord (E) until you feel it engage with the engine, then pull it out

rapidly (use both hands if necessary). The engine should start. Allow the starter cord to rewind slowly –

do not let it "snap" back.

6. WARM-UP –Allow the engine to warm-up and run smoothly. If choke is being applied, place the choke

(B) in the "RUN" position.

7. THROTTLE –Adjust the throttle control (D) for the required engine speed.

If the engine does not start, repeat step 5 onward. If the engine fails to start after several attempts, refer to

Troubleshooting.

Stopping the Engine

Stopping in an Emergency

1. To stop the engine immediately, place the engine ON/OFF switch or key switch in the "OFF" position.

Stopping in Normal Use

1. Rotate the throttle control lever so the engine is idling (slowest running speed).

2. Place the engine ON/OFF switch in the "OFF" position.

3. Place the fuel tap in the "OFF" position.

Environmental Considerations

Altitude

If the engine is being used in altitudes at or above 1500m (approximately 5000'), adjustments to the

carburettor may be required. This is because there is less oxygen in the air as altitude increases, which

effectively "enriches" the ratio of fuel to air going into the engine and the higher the altitude, the richer the

fuel mixture becomes. If the engine is being permanently operated at high altitude, it is recommended to

have an authorized service centre make the necessary carburettor adjustments. If the engine is used

occasionally at altitude (not extreme altitudes), no adjustments should be required, however, a slight

decrease in engine performance can be expected.

BCX650 Plate Compactor

Temperature

If the engine is being used in extremely cold or hot

environments; for example, desert or snow conditions, the

type of engine oil may need to be changed to suit

environmental temperatures. Oil thickens as the temperature

decreases and thins as temperature increases, which means

that if the engine oil is not suited to the temperature its ability

to properly lubricate the engine may be affected. Use the

following chart to determine the correct engine oil:

Compactor Operation

Do not operate the machine on concrete or on extremely hard, dry, or compacted surfaces.

The plate will jump rather than vibrate and could damage both the plate and engine. • When

using a compactor on asphalt, a water sprinkler should be used to help prevent the compacting plate from

adhering to the hot asphalt surface. • When using the plate on paving stones, attach the plate compactor pad

to the machine to prevent chipping, scratching or cracking the surface of the stones. • While a certain

amount of moisture in the soil is necessary, excessive moisture may cause soil particles to stick together and

prevent good compaction. If soil is extremely wet, allow it to dry somewhat before compacting. • If soil is so

dry as to create dust clouds while operating the machine, some moisture should be added to the ground

material to improve compacting.

When the machine is being used, an eccentric (off-centre) weight contained within the exciter housing is

driven at high speed by a clutch and belt drive system. This high-speed shaft revolution causes the rapid

lifting and downward ramming motion of the machine as well as imparting a forward motion. The exciter

motion provides the high-frequency vibration and force to compacting plate.

After the engine warms up, use the throttle control to increase engine speed. The plate will begin vibrating

and the machine will tend to move forward. The plate compactor is designed to run at an engine speed of

3600RPM (normally considered full throttle). Note the following:

•Running the engine at lower speeds will result in a decrease of compaction force and slower travel

speed. It may also create excessive "unsynchronised" vibrations, resulting in poor compaction, low

manoeuvrability, increased machine wear, and operator discomfort.

•In operation, guide the machine, but let the compactor do the work. Putting pressure on the handle is

unnecessary and causes wear to the vibration isolation rubbers.

•On level surfaces the machine moves forward rapidly. On uneven surfaces or inclines, light forward

pressure on handle may be required to assist the machine in moving forward.

•The number of passes required to reach a desired compaction level will depend on the type and

moisture content of soil. Maximum soil compaction has been reached when excessive kickback or

bounce is noticed.

present. It is essential to add adequate engine oil of the correct type to the engine before use –see

Checking and Changing Engine Oil. Failure to add engine oil will void the product warranty.• Do not

have the engine running during inspection and maintenance unless specifically required. • The engine should

be cool enough to touch before performing maintenance activities. • Some maintenance activities described

may be beyond the scope of some users. For procedures that you are not comfortable with or have the tools

or experience for, have the unit serviced by a service centre or qualified technician. • Do NOT use a

"pressure washer" to clean the machine. Water can penetrate areas of the unit and cause damage to

spindles, pulleys, bearings, or the engine. The use of pressure washers will result in shortened life and

reduce serviceability. • Harsh operating environments such as extreme temperatures, dust etc may

necessitate more frequent maintenance. • Maintenance frequencies are based on general factors including a

maximum use of approximately 300 hours per year. Apply common-sense when following the maintenance

schedule based on your actual use of the product. • Keep reasonable records of maintenance activities for

reference. Failure to follow the maintenance schedule, using incorrect or non-compatible accessories

or replacements parts, or general negligence may result in making the product warranty void.

To keep the engine performing at optimal efficiency, regular checks and maintenance is required. Proper

care and maintenance ensures best performance and longest service life.

The maintenance schedule below specifies preventative maintenance checks and necessary maintenance

tasks and how often they should be performed. The schedule applies to multiple engines; some engines may

not include some components, so maintenance on those components is not applicable.

Checking and Changing Engine Oil

The product is NOT supplied with engine oil, although traces of oil from the manufacturing

process may be present. It is essential to add adequate engine oil of the correct type to the

engine before use. Failure to add engine oil will void the product warranty. • Always check engine oil

level when the machine is in an upright position on a flat and level surface. • Do not use used or

contaminated engine oils. • Use only engine oils of the correct type (see Specifications). • Perform the first oil

change within the first 20 hours of use. Subsequently, change the oil every 20 hours of use. • It is

recommended that the engine be warm, but not hot, when performing oil changes. When the oil is warm it

drains faster. • Using dirty or incorrect engine oil may cause engine damage and void any warranty. •

Always use suitable tools. • Always dispose of used oil in an environmentally responsible manner and

according to regulations. • Some engines feature oil level detection, which will prevent the engine being

started or automatically stop a running engine if there is insufficient oil. • Always check the oil level and

ensure is at or near the "MAX" indicator before using the machine. • Some models may have 2 oil drain

plugs and fillers on either side of the engine –it does not matter which one is used.

Four-stroke engines require engine oil in the crankcase for lubrication of internal components. Severe or

irreparable damage may occur if the engine is allowed to run without engine oil. The engine oil level requires

regular maintenance as per the maintenance schedule.

To check engine oil level:

1. Place the machine in an upright position on a flat and level surface.

2. Clean the machine around the oil filler cap (A) so that no dirt or other material enters the engine when

the cap is removed.

3. Remove the oil filler cap (rotate left) until fully unscrewed. For machines without a dipstick, the oil level is

determined by how close the oil is to the edge of the filler hole (B). For machines equipped with an oil

level dipstick:

a. Remove the dipstick (C) and wipe clean with a piece of cloth or paper.

b. Insert the dipstick into the oil filler but do not screw it in.

c. Remove and inspect the dipstick –the oil level is determined by where oil can be seen on it.

4. Ensure that the oil level is at or just under the "maximum". If the oil level is low, add additional oil until the

correct level is reached. If the oil level is too high, drain some oil until the correct level is reached.

5. When finished, re-install (rotate right) the oil filler cap until firm. Wipe off any residual oil from the

machine.

Checking, Cleaning or Replacing the Air Filter

Operating the machine without a functional air filter may cause severe engine damage and will void

any warranty. • A dirty or oil saturated air filter will restrict air flow, which can be mistaken as fuel

system problems. Check the condition of the air filter before adjusting engine idle speed, where applicable. •

If the air filter is damaged (torn, broken, disintegrating), replace it.

The air filter is used to prevent dirt and other particles from possibly entering the engine and causing internal

damage to it. The air filter requires regular maintenance as per the maintenance schedule.

Air Filter Inspection and Cleaning

Inspect the air filter for dirtiness and debris, damage etc. Clean or replace the filter element as necessary. To

clean air filters:

•For foam filters, wash the filter in warm water and mild detergent, then rinse and allow to dry.

•For paper filters, use compressed air to blow particles from it. The air should be blown from the engine

side of the filter.

•Clean all other air filter assembly components using water and mild detergent, then dry them.

•For foam filters, place a few drops of clean engine oil on the filter then squeeze it a few times to spread

the oil through the filter material and remove any excess oil.

Air Filter Removal/Installation

To remove the air filter:

1. Unscrew (rotate left) the wing nut (B) securing the air filter cover (C) and remove the cover from the air

intake assembly (A).

2. Unscrew (rotate left) the wing nut (D) and remove the filter element (E).

To install the air filter:

1. Re-install the filter element and ensure it is seated correctly on the air intake assembly.

2. Re-install (rotate right) the wing nut and tighten by hand so that the filter element is secure. Do not over-

tighten.

3. Re-install the filter cover and secure it with the wing nut (rotate right). Tighten the nut by hand. Do not

over-tighten.

Spark Plug

If the spark plug is damaged (cracked insulator, broken or eroded electrodes etc), replace it. •

Always use spark plugs of the correct "heat range" - see Specifications.

The spark plug is used to ignite the air/fuel mixture inside the engine. The spark plug has electrodes on one

end and an electrical terminal on the other. The spark plug requires regular maintenance.

Spark Plug Cleaning and Gap Checking

The spark plug should be checked and cleaned as per the maintenance schedule.

1. Remove any carbon deposits on the spark plug (A) electrodes (B) with a wire

brush.

2. Clean the spark plug threads and the electrical terminal (C) on the top.

To check and adjust the spark plug "gap":

1. Use "feeler" or "thickness" gauges (X) to measure the existing gap. The gauge

must drag a little when being slid between the electrodes (2) –this means the

measurement is fairly accurate.

2. Adjust the gap to within specification (see Specifications). If the gap needs to be

reduced, gently tap the electrode as required. If the gap needs to be increased,

use pliers to gently pull the electrode as required.

3. Measure the gap again and ensure it is within the specified range before re-installing the spark plug.

Spark Plug Removal/Installation

1. Pull the electrical lead (B) from the terminal on top of the spark plug (A).

2. Clean the area around the spark plug so that no dirt or other material can enter the engine when the

spark plug is removed.

3. Use the spark plug tool (C) to remove the spark plug (rotate left).

To re-install the spark plug:

1. Place the spark plug in its hole and screw it in (rotate right) until "finger tight".

2. Use the spark plug tool to tighten the spark plug approximately one quarter turn (do not over-tighten).

3. Place the electrical lead over the spark plug terminal and push it down so that it connects firmly with the

terminal

Exciter Drive Belts

On new machines or after installing new belts, check the belt tension after the first 20 hours of

operation. Check and adjust the belt every 50 hours thereafter. • When replacing belts, always

replace both belts at the same time. • When installing or adjusting belt(s), ensure that the clutch and exciter

pulleys are aligned.

To ensure optimum power transmission from the engine to the exciter, the drive belts must be in good

condition and be correctly tensioned.

Checking and Adjusting Belt Tension

Correct belt tension is critical to machine performance and how long the belts will last. Inadequate tension

may cause the belts to slip, which will prevent the exciter from vibrating at the correct speed and will cause

excessive belt wear, glazing etc. Too much tension will cause premature belt failure and place unnecessary

stress on other machine parts. To check belt tension:

1. Remove the 2 bolts (A) securing the drive belt cover (B).

2. Check belt condition –if there is any cracking, fraying, or glazing, replace both belts.

3. Squeeze the belts together in the centre –belt deflection on each side should be 9mm (3/8”) to 13mm

(1/2”) with moderate pressure from your thumb or finger.

4. If the tension requires adjustment, loosen the 4 engine mounting bolts (C) slightly (do not remove) –just

enough to allow the engine to be moved.

5. Loosen the engine adjustment lock nuts (D), leaving sufficient space between the nuts and bracket for

the required engine movement.

6. Shift the engine toward the rear of the machine by rotating the adjustment bolts (E) right (clockwise) until

the belt tension is correct. Rotate both adjustment bolts the same amount so that the engine and belt

pulleys remain in alignment. If the engine cannot be moved any further and the belts remain "loose",

replace the belts.

7. Tighten engine adjustment lock nuts against the bracket.

8. Tighten the engine mount bolts.

9. Re-install the drive belt cover.

Exciter Lubrication

Do not overfill the exciter housing –overfilling can result in excessive temperature. • The oil should

be replaced after each 200 hours of operation with Dextron III, Mercon, NUTO H-32 automatic

transmission fluid or equivalent.

The exciter assembly comes pre-filled with oil, however, requires regular maintenance.

1. Remove the exciter drive belts.

2. Remove the 4 nuts (A) securing the compactor plate and exciter housing to the machine.

3. Separate the compactor plate and exciter housing from the machine.

4. Remove the plug (B) from the top of the exciter housing, then tilt the housing upside down drain all oil

from it. Examine the oil for metal chips as a warning of future issues.

5. Return the compactor plate/exciter housing to a horizontal position.

6. Fill the exciter housing with 200ml of oil.

7. Apply pipe sealant to the plug and re-install it to the exciter housing.

8. Reassemble the compactor plate/exciter housing to the rest of the machine and firmly tighten the 4 nuts.
