Safety instructions
This traing-cart may only be used as directed. This training-cart was constructed and buildt for the training of powerful dogs as for example sleddogs. Pay attention to the currently valid animal rules. It is not allowed to hang on the cart at any vehicles (Especially motorized vehicles). The driving on public roads is not allowed, because the cart is not prepared to have part with the traffic. If you are driving on forest roads you have to pay attention to the currently valid rules. These rules are different from country to country so you have to inform yourself. This training-cart is not a child toy. Keep the cart away from kids. They could hurt themselve or others.
 

Before the start
Before you start you have to check if the cart is roadworthy. Depending on how often you drive, it can be necessary to check the screws.
Depending on your terrain and number of dogs, it can be necessary to load baggage. For every dog you should have about 15 kg weight.
For example cart + musher = 135 kg means 13,5 kg each dog if you are driving a 10 dog team. That would not be enough to have the team under control! During you harness the dogs you have to fix the cart safe, for example with a paniksnap ( see figure 1). Only the sledgebrake is not sure enough!

Driving instructions

While you are driving you have to shift your weight to the inside of the bends.
In very narrow bends and high speed at

the same time you additional have to sag at the knees.
 

The sledgebrake

With the sledge brake is it possible to lock the cart on the way. If you have to go to the dogs so do it as follows:
Put one foot on the sledge brake. Hold the cart with the grips an lift it up until the

bow of the brake clicks in.To release it pull the bow to you.
Tip: Additional to the sledge brake you can loch the front wheels with the handbrake.

The suspension
The cart got a suspension in the front and in the back. The suspension in the front dosn`t need an adjustment. The suspension in the back is adjustable: Moving the spring element changes the hardness of the suspension. You have to losen the screw at the bottom of the element with a spanner SW 17 (figure 3). If you move the element towards the direction of the frame of the cart will make the suspension harder in the other direction softer. Make some tests to figure out what`s the best. If you here a metallic "clack" from the wing your the suspension is too soft.

The brakes
The brakes are the most important things of your cart. For a perfect function please pay attention to to the following: Never bend the brake ropes! The brake ropes always have to glide lightly. Depending on the stress of the ropes it can be useful to change the ropes once a saison. The brakes can be adjusted with the screws at:
- the beginning of the brake ropes down at the handbrake
- at the end of each brake rope at the wheels
By turning out the screws you shorten the length of the ropes, by turning in you lengthem them. After every change you have to fix the screws again. The brakes are adjusted the right way if you hear the brakes slipping while turning the wheel. The brake levers are additional able to be used as a hanbrake because they ca be locked in every position.
 

The drum brakes
The drum brakes are nearly maintenance-free. If the brake performance gets weaken you can rough them with sandpaper. This is also recommenden if the brakes got overheated. For this work you have to remove the corresponding wheel. While you are working on the brakes please pay attention to the following: Never oil or grease on linings or drum! If the linings are nearly worned out till the sheets you have to replace them. Occasionally one drop of oil on the brake lever keeps it going.

The combined feet and handbrake
Foot- and handbrake are an integrated whole. You can fix the pedal with the handbrake. Tip: To remove the lever arm you also can kick it with your foot. That is quick and you don`t have to bend down.

The hydraulik brakes
The hydraulik disk brakes are much more stressed than the drum brakes. The brake linings must be changed often. How often depends on the terrain you are driving. It is possible that the linings are attritioned after 250 Km! Tip: Control the linings every 50 Km till you know how often you have to change them.
 

Changing the slides
1. The linings are holded with a pin.
2. This pin is secured with a ring.
3. Remove the ring with a screwdriver.
4. Drive out the pin (figure 4) with a plastic hammer from the side of the wheel. 5. Take out the spring.
6. Take out the linings.
7. Press the pistons back so far as possible. Use two screwdrivers simultaneously from two sides. Never use force! Don`t damage the seal!
8. Put in the new linings and fix them with pin and spring.
9. Secure the pin.
If you think you are not capable to do this work so please contact a garage.
