5 minHow to use the rammer (jumping-jack)
The rammer compacts by impact: the shoe jumps and kneads the soil. It's the king of the narrow trench and cohesive soil (clay, silt).

- 01
Pre-start check
Engine and percussion-case oil level, clean air filter and fuel. Shoe free of cracks and loose bolts.
- 02
Start at idle
Start and let it warm a few seconds at idle. The rammer shouldn't jump until you give it throttle.
- 03
Full throttle to work
At half throttle it bounces and gets unruly. Full throttle delivers all the impact force and it self-advances: you just steer.
- 04
Compact in lifts
Lifts of 20–30 cm max. Thicker than that and the bottom never reaches density. Let the machine set the travel pace.
- 05
Overlap your passes
3 to 4 passes per lift, overlapping each lane. Corners and up against the wall — that's where the rammer beats the plate.
Do this
- Keep the shoe flat against the ground, not tilted.
- Bring the soil to optimum moisture: it compacts far better.
- Let it self-advance; your job is to steer, not push.
Avoid this
- Don't expect miracles on dry loose granular: cohesive soil is its job.
- Don't run it half-throttle — it bounces and punishes your wrists.
- Never leave it running while laid on its side.
Safety
- Steel-toe boots, anti-vibration gloves and hearing protection.
- Keep feet clear of the shoe: the impact is unforgiving.
- In a trench, check the slope and shoring before climbing down.
