1.4. Main Parts of the Machine
The ice resurfacer consists of three main parts. The front frame contains the snow tank, batteries, and the hydraulic unit. The back frame contains the auger, the cooling water tank, and the operator’s compartment, and is jointed to the front frame. The joint enables driving on uneven surfaces – e.g., when emptying the snow tank outside. The back frame is attached with a sled, which is primarily used for the ice maintenance. The sled contains the shaving blade, which must be handled with extreme care.

1.4.1. Controls
To ensure easy use during ice maintenance, the ice resurfacer’s controls are located close to the operator.
Figure 2. Operator’s compartment
7
1.4.2. Driving Controls
The ice resurfacer is steered with a steering wheel, which turns the front wheels of the machine to the desired direction. You can select the direction of the machine (forward or backward) with the direction selector, and control the speed by means of a pedal. To apply brakes, reduce pressure on the pedal or remove your foot from it; the hydraulic system will then apply the brakes automatically.
Figure 3. Pedal
1.4.3. Meters
1.4.3.1. Operating Hour Meter
The operating hour meter indicates the total operating hours of the machine in hours. The meter starts running once the electrical system is turned on by turning the ignition key.
8
1.4.3.2. Oil Window
You can check the oil level in the oil tank from the oil window on the side of the hydraulic oil tank. When the machine is on an even surface, the oil surface level should be visible in the window. The system contains a total of 60 litres of hydraulic oil.
1.4.3.3. Dirt Indicator
The dirt indicator on the return oil filter indicates how dirty the filter is. Once the indicator reaches the red area, the filter must be replaced immediately, even if the normal change interval has not yet passed.
Figure 4. Oil window and return oil filter dirt indicator

1.4.5. Water System
The ice resurfacer’s water system consists of the following parts: The water tank is filled via the main water valve and the filling pipes, and the cooling water flows behind the sled from the tank under its own pressure. You can adjust the amount of water by using the cooling water lever. The towel is used to spread the water onto the ice to form an even surface.
1.4.5.1. Filling the Water Tanks
The ice resurfacer has a fire hydrant connector and a main water valve under the operator’s seat for filling the water tanks.
The water must be cooler than 80 °C. If the water is too hot, it can soften the hoses, which can inhibit water flow.
12
Fill the water tank in the following way:
1. Attach a filling hose that has been attached to the water pipeline network:
The filling hose should have a fire hydrant connector that is compatible with the machine’s connector.
2. Open the main water valve of the ice resurfacer.
3. Open the pipeline network tap.
4. Close the pipeline network tap once water flows from the overflow tube or when the tank contains the desired amount of water.
5. Close the main water valve.
6. Detach the fire hydrant connector from the machine.
Figure 7. Fire hydrant connector and main water valve (Note! The main water valve handle may be of different colour and shape to the one shown here.)
1.4.5.2. Cooling Water Handle
You can control the amount of cooling water with the cooling water handle on the right side of the control panel. By pushing the lever forward, the cooling water valve opens and water starts flowing behind the sled. Pushing the lever further forward increases the cooling water flow. You can stop the water flow by pulling the handle to its extreme back position.
13
Figure 8. Cooling water handle
1.4.6. Electrical System
The electrical system consists of the following parts:
- 12 V battery which powers the control panel.
- 24 V hydraulic control unit which controls the hydraulic pump.
- Control panel for controlling the machine.
1.4.7. Seat
Adjust the position of the seat before operating the machine. The seat should be adjusted so that you can easily reach all of the controls. You must have unobstructed visibility around the machine, including behind it. Always use the seat belt when driving the ice resurfacer.
14
1.5. Using the Machine
1.5.1. Starting
Start the machine according to the following instructions:
- Check that the ignition key has been turned to its extreme left position, the direction selector is in its middle (neutral) position , the motor rotation speed is low, and all buttons are in their upper or middle positions (indicating that the functions controlled by them are off).
- Turn the ignition key to the right; i.e. from the vertical position to the current-on position.
- Turn the key to the start-up (extreme right) position to start the motor.
- Let the motor run for 30 seconds before starting work.
1.5.2. Moving
To move the ice resurfacer, select a driving direction with the direction selector and depress the pedal. The more pressure you apply on the pedal, the quicker the machine moves. Before moving the machine, fasten your seat belt. While driving the machine, keep in mind that the grip of the studded tyres on both wet and dry ice is limited and that driving too quickly can result in uncontrolled movement of the machine. The machine must not be driven on sloping surfaces or steep hills.
1.5.3. Reversing
To back up, select the backward direction with the driving direction selector. You will hear the back-up signal and the machine will back up. When backing up, control the speed of the machine with the pedal. Please note that the ice resurfacer goes backwards as quickly as it does forwards.
15
1.5.4. Ice Maintenance
The following sections describe the tasks and functions associated with ice maintenance.
1.5.4.1. Side Brush
The side brush is used for maintaining the sides of an ice rink. The brush removes snow and ice flakes from the side areas that cannot be reached by the sled. When the side brush is used, the doors of the ice rink must be closed to avoid damaging the brush on door jambs or other obstacles.
1.5.4.2. Sled
The sled is lowered to the ice and kept pressed down during ice maintenance.
Hydraulic cylinders press the sled against the ice and ensure that shaving results are even. Lift the sled when you leave the ice so that neither the shaving blade nor the auger comes in contact with any obstacles.
1.5.4.3. Auger
The auger moves the snow and ice flakes created by skaters into the snow tank.
When necessary, you can stop the auger during operation, in which case the snow is gathered in the sled. You can run the auger in the opposite direction to remove possible blockages.
1.5.4.4. Water Spreading Towel
The water spreading towel spreads cooling water evenly onto the ice. The towel is lowered and lifted hydraulically. Dampen the towel before ice maintenance: a dry towel does not spread water evenly, and parts of the dry towel may remain above the ice surface, resulting in streaks on the ice.
16
1.5.4.5. Cooling Water
Cooling water finishes the shaved ice surface. You can change the thickness of the ice by adjusting the amount of water and the shaving depth. Excessive use of cooling water results in flooding, whereas too little cooling water results in dry and uneven streaks.
1.5.4.6. Emptying the Snow Tank
Before emptying the snow tank, ensure that the snow can fall freely from the opening tank and that no-one will be in the path of the falling snow. To empty the snow tank, press the button until the snow tank cover and the tipping cylinder are lifted to their extreme upright position and the movement of the tank stops. If any snow remains in the snow tank, lower the tank slightly by pressing the button down and then lift the tank back to its upright position. In addition to emptying the snow tank, you can remove snow from the auger by running the auger in the opposite direction.
1.5.5. Storage
The ice resurfacer should be stored at a room temperature of above 20 °C, at normal humidity levels. When the ice resurfacer is not in use, switch off the power and close the gas bottles. The snow tank must be lifted up so that the tank can dry and air can circulate freely under it. Use the maintenance support to ensure that the snow tank remains up. Service all parts of the machine, and grease all of the joints. In addition, protect the machine from humidity and store it in sufficiently warm conditions (see above).
1.5.6. Towing
If the machine needs to be towed, for maintenance or other reasons, do the following:
Close the brake release lever on the front side of the cooling water tank.
17
Figure 9. Brake release lever
Release the brakes by turning the hand pump valve (1) left.
Figure 10. Hand pump
Pump the hand pump to release the brakes (at least 10 times). Close the hand pump valve (1) by turning it to the extreme right (as shown in the figure).
Switch wheel motors to neutral.
18

2. MAINTENANCE
All parts of the ice resurfacer must operate flawlessly in order for the machine to function properly. We recommend that the operator monitors the condition of the parts and carries out all necessary maintenance procedures as soon as possible, to avoid damage. The machine should be serviced twice a year. Maintenance tasks for various parts and parts that require special attention are listed below.
2.1. Blade
Monitor the condition of the blade continuously. If the blade is damaged or blunt, the shaving result will be noticeably different from that of a sharp blade. The quality of the ice affects the durability of the blade. Once you become more experienced in the use of the machine, you will be able to recognise when the blade is blunt and determine when it must be replaced.
Be extremely careful when handling the blade!
Change the blade according to the following instructions:
- Place the sled on supports
- Place boards or other supports under the blade
- Remove the cover sheets from the top of the sled
- Open the screws that attach the blade, starting from the sides and moving toward the centre
- Let the blade fall onto the boards
- Pull the old blade from under the sled
- Lift the old blade into a blade cover and secure the mounting nuts
- Mark the blunt blade
- Remove the new blade from its blade cover
- Lift the new blade onto the boards
- Push the new blade under the sled
- Lift the blade from one end and partially tighten the mounting screw
20
- Lift the other end of the blade and tighten as above
- Attach the rest of the screws, but don’t tighten them yet
- Begin tightening from the centre screw, moving toward the side; finish one side before starting the other
- Tighten the screws on the other side as above, moving from the centre toward the side
- Place the cover sheets back on the sled
- Lift the sled and then remove the boards from under the sled
- Adjust the blade in a horizontal position by turning the adjustment screws so that the blade’s entire length shaves the ice
2.2. Hydraulics
Keep the hydraulic system clean, and watch out for possible leaks. Monitor the oil temperature to detect possible faults in the hydraulic components and to avoid faults that prevent use of the machine.
2.2.1. Oils
Check the oil level daily. After use, take note of the oil temperature. For a new machine, the oil must be changed when the operating hour meter reaches 100 hours. The next oil change is carried out when the operating time reaches 500 hours. Thereafter, the oil should be changed following every 500 hours of operation. If the machine is not used for an extended period of time, check the oil quality and, if necessary, change the oil. Fill the oil tank through the cap in the return oil filter to avoid introducing any impurities to the system.
21
Figure 13. Fill the oil tank through the return oil filter cap
2.2.2. Filters
The oil tank contains two filters. The high-pressure filter is located behind the tank and the return oil filter in the right front corner of the tank. Change the filters after every 500 hours of operation. The return oil filter must be changed sooner than that if the filter’s indicator reaches the red area.
Figure 14. Return oil filter on the left, high-pressure filter on the right
2.2.3. Hoses
Keep the hoses clean, and monitor the tightness of hose joints. Check the hoses for possible wear and tear, and replace any damaged hoses.
22
2.2.4. Valves
Check the operation of the hydraulic unit valves daily by using all of the machine’s functions. Check that oil does not leak from the valves, and keep the valves clean. Qualified ICECAT service personnel will take care of valve adjustments for you.
2.2.5. Pumps
Monitor the temperature and sounds of the pumps. Should you hear unusual sounds from the pumps, or should they overheat, contact ICECAT service personnel.
2.2.6. Hub Motors
Check the operation of the parking brake daily.
2.2.7. Cylinders
Check the operation of the cylinders daily. Pay special attention to the condition of the cylinder shanks. Any oil leaks at the base of the shank indicate broken seals. When storing the machine for an extended period of time, make sure that the cylinder shanks are placed inside the cylinders.
2.3. Mechanics
2.3.1. Motor
Maintain the motor according to the manufacturer’s instructions – see below. The motor’s maintenance manual is attached to this user manual.
23
2.3.2. Bearings
Grease bearings with grease nipples once a week, especially the vertical auger bearings. Check and grease tie rod ends once a week. Check the condition of slide bearings once a week, and lubricate the sled’s brass bearings and adjustment screws every week. The condition and operation of all bearings must be checked during service work.
2.3.3. Screws and Nuts
Check the tightness of screws and nuts before every use, and check the bolts of the aluminium wheels every day.
Keep the blade adjustment screws lubricated.
24
2.3.4. Belts and Chain
Check the tightness and condition of the belts and the chain every week.
Replace any worn parts immediately.
2.3.5. Gas Springs
The blade block is pressed against the ice with gas springs. A wavy shaving result indicates that a gas spring is damaged. Replace the gas springs when necessary.
2.4. Water System
Lime and other impurities must be cleaned from the immersion pump, tanks and hoses during every servicing. Monitor the condition of the water hoses and the water flow speed. Any anomalies in the water system must be fixed immediately.
Open and clean the water valves once a month. Replace the water spreading towel immediately if it is broken or starts to fray.
2.5. Electrical System
All electrical equipment is splash-proof. Should water be spilled onto the electrical equipment, dry it immediately. When in doubt, please contact
