DO NOT USE at more than 15km/hr.
The small pneumatic wheels sold by Fallshaws are designed for light duty equipment, hand pushed, or towed at no more than a fast walking pace. They are not designed for high-speed use.

INFLATE to 210kPa (30psi). Reinflate to 210kPa (30psi) if pressure falls to 140kPa (20psi). This pressure is chosen to allow for the tyre to give a good cushioned ride.

SAFETY NOTE: Pneumatic tyres may have a higher pressure marked on them for when used on different rims, but in this tyre / rim combination the maximum pressure to be used is 210kPa (30psi).

WARNING: Plastic rims are marked near the valve "MAX PRESSURE 210kPa (30psi)". Inflation over this pressure may cause the rim to fail, and is UNSAFE. Steel rims may be inflated to 350kPa (50psi) or the max pressure marked on the tyre (whichever is the less). Inflation over this pressure, may cause the tyre to fail, and is UNSAFE.

ROUTINE MAINTENANCE:
PRESSURE:
Check weekly with a tyre pressure gauge available from automotive parts suppliers. If the pressure has fallen to 140kPa (20psi), it should be reinflated to 210kPa (30psi).
Use a normal motor tyre pump, or take the wheel to a petrol station and use their air. DO NOT OVER INFLATE.
(BEWARE: Petrol station air can go to 700kPa (100psi) - very dangerous).
Note: These small sized pneumatic tyres do not hold their pressure for as long as a car tyre (which has a much greater volume of air). You can expect they should not loose more than 70kPa (10psi) in 4 weeks. Slow leaks may indicate the need to replace the tube valve inner. Quick leaks probably indicate a puncture.

WHEELS:
Check the tyre prior to use, and after rough usage for bulges or cuts, or bending of the rim, as these can lead to failure in use. Tyres should be replaced if the bulges are more than 3mm high, or the cuts longer than 5mm, or deeper than 2mm. Rims should be straightened or replaced.

IF STEEL WHEELS are bolted together:
The wheel nuts should be tight before and after use. A torque of 30Nm is correct (that is approx what you will get pushing with 3 fingers on to a spanner with a length of 220mm). If nuts are coming loose, the bolt and nut and/or shake proof washer should be replaced, and tightened to 30Nm.

BALL BEARINGS:
Are pre-packed with grease and shielded, and will not normally need to be regreased in ordinary usage (that is, if kept dry, or only sprayed with water occasionally). If the bearings are immersed in water, the bearings should be blown dry with compressed air, and then lightly re - oiled with about 10 drops of light machine oil. If the bearings become rough or very loose through misuse, they should be replaced. (Replacement bearings are available as a spare part).

PUNCTURES:
A rapid reduction in pressure usually indicates the tube has been pierced.
This necessitates removing the tube and repairing it with a standard automotive tyre repair kit.
WARNING: Always completely deflate the tube before attempting a repair. NEVER loosen the bolts holding a divided rim together unless the tube is completely deflated.
It is VERY DANGEROUS to loosen wheel nuts unless the pressure is ZERO.
If the rim is either moulded in one-piece, or has steel sides welded together, it will have a drop centre (that is, the centre of the well of the rim has a smaller diameter than the bead on which the tyre fits). Use tyre levers to get the outer tyre down in to the well, so the tube can be removed. Use the same techniques as for a motorcar tyre. If the wheel is two-piece, that is the sides are bolted together, it will not have a well, and the sides will have to be unbolted to allow tube or tyre to be removed; and then bolted together again after repair. See WARNING above.

OUTDOOR USE:
Constant exposure to direct sunlight can cause a 30% reduction in the effective life of both rubber and plastic. Store those wheels out of the direct sun light. If they develop cracks due to hardening they should be replaced.
