5.12 Checking & Changing
Blower Gear Case Oil
The blower gear case oil level should be checked
daily or at least every 50 hours of operation. The
oil should be changed every 500 hours.
When changing or checking the gear case oil,
always clean the area around the breather and
overow plugs before they are removed. This will
reduce the possibility of dirt and debris from enter-
ing the gear case when the ll plugs are removed.
Checking The Gear Case Oil Level
1. Make sure the waterblasting system is shut-
down with the truck in the service position and
on level ground.
2. Remove the overow plug on the side of the
gear case. The oil should be within 1/4” of the
bottom of the plug threads.
3. If the oil is low, remove the breather plug and
add oil until the oil level is even with the bot-
tom of the overow hole.
4. Replace the breather and overflow plugs.
