Lubrication

 

 

1.  Check the lubrication level once a month and change 

after  every  100  hours  of  operation  or  at  least  every 
spring  and  fall.  Under  severe  conditions  where  pump 
has  been  used  continuously  at  high  output,  change 
more frequently. 

 

2.  Always  fill  to  the  bottom  of  the  plug  hole  labeled 

“Oil 

Level”. Do not Overfill. 

 

NOTICE

 

 

If fluid level is low, locate the source of the leak 
and repair. If the fluid level is high, loosen the drain 

 

3.  Note that the breather may be removed and the hole 

used as the lubricant fill. 

 

4.  Capacities  shown  are  approximate,  quantities  listed 

vary based on ratio and/or mounting orientation. 

 

5.  Be sure to clean the drain plug and breather. 

 

6.  Synthetic oil substitutes are acceptable.
