5.4 - Changing the Hydraulic Oil
When using Lassco Wizer Hydrol HL, the Hydraulic Oil should be changed every 2100 Machine Hours. Machine
Hours are defined as the period of time that the Table Motor is turned on and pumping oil, regardless of being oper
-
ated or not (Even when not drilling, the Table Motor is pumping oil continuously).
If an equivalent oil (other than Hydrol HL) is used, this maintenance schedule may vary, depending on the manufac-
turer’s specifications. Some hydraulic oils break down when their temperature exceeds 120 F (48.9 C). Hydrol HL
will maintain its consistency until it reaches 210 F (98.9 C)
Access the Oil Tank by removing the eight (8) hex screws on the rear of the machine which hold the Back Cover in
position. Remove the back cover.
To drain the Hydraulic Oil: Remove the Cap by twisting it counterclockwise. Drain the Hydraulic Oil using either a
pump system to pump the oil out of the machine, or use a syphon system to drain out the oil. It is important to remove
as much of the oil as possible.
Discard the used hydraulic oil making sure to follow all local regulations when disposing.
