Theraplay IMP, Owner'S Manual

5  CRANK ARMS

The crank arms are fixed onto the Bottom Bracket Axle by cap 

Screws, these are located under the black plastic cap on the crank 

arm. If either crank feels loose, tighten securely with the M6 Allen key 

provided.  NOTE: Failure to maintain the crank arms can result in the 

crank arms and the Bottom Bracket axle being damaged.

6  PEDALS

Each pedal has a different thread. Forcing the wrong pedal into the 

wrong crank arm will destroy the threads in the crank arm. To prevent 

this error, insert the “L” marked pedal into the left crank arm and “R” 

into the right. Then tighten securely with the wrench.

NOTE: Left and Right are determined from the riding position on the 

tricycle. Pedal sandals if fitted should be tightened against pedals using 

the brackets and nuts. The brackets fit to the underside of the pedals 

and they should be securely tightened in place.

7  CHAIN 

(See Diagram 2)

It is recommended that a 3 in 1 or similar oil is used to lubricate the 

chain. Ensure that the chain is properly tensioned, if there is more than 

1/4" slack in the middle of the chain then it needs tensioned.  This can 

be achieved by loosen the M12 Nyloc Frame Stud Nuts and the M8 

Frame Cap Screw and then pulling the mainframe and rear axle in 

opposite directions and then tighten the M12 lock nut and M8 screw. 

Care should be taken not to overtighten the chain as this will make 

the tricycle difficult to pedal.     

8  HANDLEBARS

Ensure that the handlebars and handlebar stem are secured tightly. It is 

dangerous to ride a tricycle if either is not properly secured. Do not 

adjust handlebars beyond the maximum mark.

9  SADDLE

Ensure the seat pillar is secured tightly. The saddle should sit squarely 

on the seat pillar and should not be extended beyond the maximum 

marker hole.

10  TYRES

Check tyres for proper inflation pressure as indicated on the sidewall. 

If the tyre is worn or the inner tube is punctured, repairs can be made 

to the rear wheels without removing the wheel from the axle. The 

front wheel will need to be removed from the front fork.

11 POSITIONING SUPPORT

Ensure that all positioning supports are properly secured. All screws 

should be tightened.

12  PULLEY CORD

The footsandal pulley cord is made of nylon. Should the cord start to 

wear, heat slowly with a match or candle, until the cord bonds 

together. Do not overheat or the cord will melt. Regular checks 

prolong the life of the cord. Ensure that it is running freely through 

the pulley wheel. A silicone spray ensures a smoother operation.

13  ADJUSTABLE  STEERING  STOP

Ensure that this is adjusted to suit the riders ability.

MAINTENANCE  INTERVALS

Keep all painted parts cleaned and waxed for a long lasting lustre.

• Check tyres for wear

• Check wheel alignment and for loose spokes

• Check brakes for adjustment, worn cable and worn brake blocks

• Clean and adjust all bearings and cones

• Check chain for adjustment and grime

• Check for loose bolts and nuts

• Check Free Wheel for excessive side-to-side movement

WARNING! 

Like any mechanical device, a tricycle and its 

components are subject to wear and stress. Different materials and 

mechanisms wear or fatigue at different rates and have different life 

cycles. If a component's life cycle is exceeded, the component can 

suddenly fail, causing serious injury. Scratches, cracks and 

discolouration are signs of stress-caused fatigue and indicate that a 

part is at the end of its useful life and needs to be replaced.
