3 questions on cleaning and service: 1. I'm a big fan of blowing my Lazer off with air after mowing... It's quick and easy and does a good job. Just wondering, is there any place on the Lazer where I shouldn't blow air? Such as under the seat around the hydros, or around the motor...? 2. Just coming up on the first 25 hrs, and first lube, is there any certain grease Exmark recommends? 3. I have the older air filter (2001 model), is it all right to remove it and blow it out with air, and how frequently should this be done? (Mowing about 6 acres weekly) Thanks.
