USICERINKS.COM MAY.JUNE.2017 / 49 ing the ice is to install a hydraulic oil cooler on your IR. The IR hydraulic fluid will heat up and expand more than nor- mal as you do a number of consecutive shaves. If the fluid does not cool suffi- ciently in between shaves it could over- flow, causing a potentially dangerous situ- ation for you and a lengthy interruption to the process. A fluid cooler should allow you to drive the IR longer while avoiding this potential interruption. Once the ice is relatively level, continue shaving using varying full-ice patterns to ensure the ice is being shaved evenly. Sand floors expand and contract differ- ently than concrete floors, and the sand shifts over time. Therefore, there will be several high and low spots in the floor. As the ice becomes thinner, you will want to frequently walk the ice surface to identify high spots where the paint and sand is close to being exposed. As areas of the ice are shaved down to the sand surface, you will want to mark those areas with either traffic cones and/or a bright colored spray paint so you can shave around them. Identifying these areas is very impor- tant for several reasons. First, once the IR blade starts shaving into the white ice paint it will start to dull quickly, so you will need to be prepared to change the blade frequently from this point forward. Secondly, as you shave through the paint and the IR blade hits an area of frozen sand it will render the blade unusable, and the blade will need to be replaced immediately. Finally, polypiping will move with the floor, so there could be a chance of shaving into a pipe as you go over exposed sand with the IR blade. It is unlikely that you will be able to remove all of the ice and paint from the floor with the ice resurfacer due to the high spots. When you can no longer get to all of the remaining paint, it is a good idea to use box fans to melt the ice over those areas, and use a squeegee and wet- dry vacuum to remove it. The goal is to minimize the amount of ice paint that makes its way into the sand. Ice paint in the sand will cause heat transfer issues and must be removed before the next ice install.
