4. Draining And Flushing The Reservoir
Drain, clean and replenish the reservoir with high-grade, approved Power Team hydraulic fluid yearly or
more often if necessary. The frequency of fluid change will depend upon the general working conditions,
severity of use and overall cleanliness and care given the pump�
IMPORTANT:
Clean the exterior of the pump first. After draining and flushing the reservoir, drain and clean the other
hydraulic system components (hoses, cylinders, etc.) before connecting them to the pump again. This
will help prevent contaminated fluid from entering the pump.
Refer to Table 1 for your reservoir type.
