The standard answer is about every 100 scrapes. The reality is it all depends on the conditions in which you are operating. For example an outdoor rink with dirt and leaves in the ice will wear faster then an indoor rink with consistent ice temperatures.
For Olympia's equipped with the wash water system; to
attain the best ice making results the wash water system
should be used during every flood. The wash water system
sprays water from the sides of the conditioner into the
center in front of the squeegee creating slush. Excess water and slush is then vacuumed up, taking with it any dirt or debris from the ice. In addition to removing small debris from the ice surface, any snow left behind the blade is turned into slush by the wash water and is pushed into cracks in the ice by the squeegee. The water is filtered and then returned to the wash water tank.
Wash water impellers should be changed once a year. In some cases impellers will need to be changed more often due to premature break down caused by little to no water flow. This can be caused by plugged water nozzles on the wash water system or an improperly adjusted wash water pickup height .
The horizontal auger drive chain should be kept at a reasonable tension at all times. If too loose, the sprockets and chain will wear out prematurely. If too tight, the sprockets, chain and auger bearings will also wear out prematurely. To adjust the chain tension, loosen the motor mount plate bolts and slide the motor mount until you get the proper tension, Allow 1/4 to 1/2 inch (.048cm to .196cm) play then re-tighten the motor mount plate bolts.
Just because an oil filter screws on or looks right, does not mean it's the right one for your engine. Each filter is manufactured to meet specifications for maintaining the correct oil pressure, volume of oil flow, pressure relief valve opening rates, and so on. Always select only an oil filter designed and built specifically for your Olympia Ice Resurfacer. Check your owners manual or contact your dealer for details.
During normal ice resurfacing operations be sure the ice surface is free of debris. If the vertical auger picks up debris, such as a puck, it could eventually jam at the top of the auger thus blocking the path of the scrapings into the snow bin. If this does happen, the first thing you have to do is determine if the obstruction is in the horizontal or vertical auger. First try reversing the auger. If that doesn't clear the obstruction, then take the two quick couplers hoses off of the conditioner and hook the hoses directly together, thus bypassing the horizontal auger motor. Push the elevator button or lever and the vertical auger should spin. If it does then the jam has occurred in the horizontal auger.
In the case of a jam occurring in the horizontal auger, you first have to make sure the two quick couplers are attached to the horizontal auger motor. Remove the cover plate on the drivers side. Using a pipe wrench turn the auger by hand and whatever is jamming the auger will turn back out. Replace the cover plate, restart the engine and make sure the auger turns freely. The chain drive for the auger should be reasonably free moving with a quarter to half inch play at all times. If it is loose, simply back off the motor mount plate bolts and slide the motor until you get the proper tension, then tighten the bolts.
If the vertical auger does not spin, the blockage has likely occurred in the vertical auger. To un-jam the vertical auger, press the reverse button or lever to the auger. If it doesn't reverse, then shut the engine off and remove the key. Using a half-inch wrench, remove the two bolts on the cover plate at the top of the blower head. Then remove the remaining four bolts around the blower head and remove the bolt and hose clamp. Now lift the blower head from the unit making sure not to lose the gear ring inside on the drive coupling. Usually the debris is jammed near the top of the auger but in case there is more debris inside, lift the auger straight out and flush out any ice or debris that was causing the jam. Once cleared, slide the auger back into its original position on top of the stub shaft. Replace the gear ring. Now set the blower head back down on top of the vertical auger tube. Re-install the four bolts in the bottom of the blower head along with the bolt and hose clamp and tighten. Make sure there is a 1/16 (1.6 mm) of an inch between the gear ring and the top coupling half. To adjust, loosen the 2 set screws on the top coupling. Use a screwdriver to adjust the spacing then re-set the set screws on the top coupling. Re-install the cover plate. Reconnect the two quick couplers to the horizontal auger motor. Turn the ignition on and press the elevator button or lever and resume normal operations.
Proper service and repair procedures are vital to the safe, reliable operation of your OLYMPIA Ice Resurfacer as well as the personal safety of those performing the repairs. Standard safety procedures and precautions (including use of safety goggles and proper tools and equipment) should be followed at all times to eliminate the possibility of personal injury or improper service which could damage the Olympia or compromise its safety.
