Reversible Plate Compactor

Also called Reversible plate · Reversable plate · Forward/reverse plate

A plate that runs forward and backward, so it works in spaces where you can't turn a forward plate around.

Petrol engine

Overview

A reversible plate drives forward and backward from the same control handle, so it never has to be turned around. In a dead-end trench or hard against a wall, that is the difference between a machine that fits and one that does not.

Working back and forth over the same ground also lets it build compaction in one spot, which is why it suits asphalt and harder base materials, foundations and backfill against walls.

It is still a plate, so cohesive clay is a rammer's job.

Change direction smoothly with the control handle rather than slamming it between forward and reverse — the hydraulic control does not take kindly to it.

Troubleshooting

Won't change direction or reverse is weak

Checks to try, in order

  1. Push the direction control through its full travel.
  2. Look for hydraulic oil at the handle and the control hose.
  3. Make sure the engine is at full throttle.

Low hydraulic oil or a leaking control hose needs the workshop.

Reference draft — always follow the manufacturer’s manual.

Engine won't startShared · Petrol engine

Likely causes

  • Fuel valve or switch off
  • Stale fuel
  • Low oil sensor
  • Choke position
  • Spark plug cap loose

Checks to try, in order

  1. Turn the fuel valve ON and the engine switch to ON.
  2. Cold engine: close the choke. Warm engine: leave the choke open.
  3. Check there is fresh petrol in the tank — stale or water-contaminated fuel is the most common cause.
  4. Check the engine oil. Many engines have a low-oil shutdown that stops them starting when oil is low or the machine is on a slope — top up and set the machine on level ground.
  5. Make sure the spark plug cap is pushed fully onto the plug.
  6. Pull the starter rope with a smooth, firm pull — don't let it snap back.

If the starter rope is locked or unusually hard to pull, stop — don't force it. Tag the unit and return it to the workshop.

Reference draft — always follow the manufacturer’s manual.

Starts, then stalls or runs roughShared · Petrol engine

Likely causes

  • Choke left on
  • Blocked air filter
  • Low fuel
  • Low-oil shutdown

Checks to try, in order

  1. Open the choke gradually once the engine has warmed up.
  2. Check the fuel level and that the fuel cap vent isn't blocked.
  3. Check the air filter — a dusty filter chokes the engine. Tap it out or swap it.
  4. Check the oil level again; the low-oil sensor can cut the engine on uneven ground.

Reference draft — always follow the manufacturer’s manual.

Smell of fuel or a visible leakShared · Petrol engine

Checks to try, in order

  1. Switch the engine off immediately and move away any ignition sources.
  2. Turn the fuel valve OFF.
  3. Check the fuel cap is seated and look for a wet fuel line or carburettor bowl.

Don't run a machine that is leaking fuel. Tag it out and report it.

Reference draft — always follow the manufacturer’s manual.

Safety

  • When reversing, look behind you. Operators can get pinned between the handle and a wall or obstacle.

For petrol engine

  • Refuel only with the engine off and cool. No smoking or open flames nearby.
  • Exhaust contains carbon monoxide — never run it indoors, in trenches or in enclosed spaces without ventilation.
  • Wear hearing protection, safety glasses and safety boots.
