11. Tyre fitting instructions
Attention: Remove all weights from the rim before you start working with the machine.
11.1 Breaking the bead
Please take care when using the bead breaker, the arm presses with a force of 2500 kg and moves with a great jolt.
This could lead to injury if wrongly operated.
Be sure to let the air completely out of the tyre by removing the valve core before trying to press off the tyre.
Open the arm with the lever by hand and roll the wheel in up to the desired point. Press the rim against the rubber support on
the machine, and place the shoe (Fig. 7) 10mm away from the rim.
Press the bead pedal and the shoe will press against the tyre, repeat this action in various positions on both sides of the
wheel until the tyre is completely free from the rim.
11.2. Clamping the rim
- Make sure that all weights are removed.
- Clamp the rim using pedal (H), making sure that the wheel is in the middle of the turntable.
- Press the tyre down with the assistant arm (P) to aid with the lubrication (Fig. 6).
- Lubricate the tyre and remove.

11.3. Removal of the tyre
To avoid accidents always keep hands and other body parts away from moving parts when operating.
- Place the mounting head on the rim using the swing arm and adjust the distance, press the button on the swing
arm to fix the position. The mounting head will automatically lift 2 or 3 mm.
- Insert the tyre lever between the tyre and right side of the mounting head and pull the tyre over the mounting head.
(See Fig. 7-8).
Attention:
With spoked rims there is a danger of damaging the rim please use the plastic mounting head
(available as accessories).
Caution:
If the wheel is fitted with an inner tube it is recommended to place the valve approximately 10 cm to the left of the mounting
head to avoid damage to the tube.
- Hold the tyre lever in position (Fig. 8) and press the pedal (J), the turntable will turn clockwise and the tyre will be
forced over the mounting head. Keep pedal pressed until the tyre is completely removed from the rim.
- When fitted remove the inner tube.
- Repeat the steps to dismount the back side of the tyre and remove from rim.

11.4. Mounting the tyre
Check tyre and rim,
Attention: Be sure that tyre and rim are of the same size to avoid accidents.
Check for damage on the rim and tyre, if damaged it should be replaced.
Take extra care with aluminium rims as hairline cracks are difficult to see and these should not be used.
Mounting the tyre:
- Replace the valve.
- Lubricate the tyre with appropriate paste.
- Clamp the rim, if it was removed.
- Turn the valve to the top position next to the mounting head.
- Place the tyre according to the markings in the right direction of rotation over the rim.
- Adjust the mounting head as in description 13.3.
- Be careful not to trap fingers when mounting tyres, keep hands away from the rim when turning the wheel.
- Place the tyre over the front side of the mounting head and push the tyre down over the rim. (Fig. 9)
- Press the turntable pedal (J) until the tyre drops completely over the rim.
- If an inner tube is fitted then replace it before continuing with the front side of the tyre.
- Repeat the steps for the front side of the tyre.

12. Inflating the tyre
Warning
Important: Inflating tyres can be very dangerous, always follow safety instruction to avoid
serious injury.
Tyres can explode due to the following:
- The rim and tyre are of different sizes.
- The tyre or rim is damaged.
- The tyre pressure is over the maximum manufactures recommendation.
Inflating the tyre
- Remove the valve cap and take out the valve core.
- Hold and push the nozzle clamp over the valve completely and release the clamp.
Pump the tyre up to approximately 3 bar to ensure that the tyre is properly seated and sealed not forgetting to
constantly check the pressure to avoid over inflating.
- Check that the tyre is evenly seated use tyre guidelines if available, replace the valve core and inflate to
manufactures recommended pressure.
