Extreme Duty Snow Blower Operation and Maintenance Manual

Operation

Machine Hydraulic Rating

IMPORTANT

The  snowblower  is  rated  for  a  specific
hydraulic  flow  that  should  match  your
machine  hydraulic  capacity.  Operating  the
snow blower at a higher than rated flow will
over-speed the snow blower and may cause
severe 

damage 

to 

snow 

blower

components,  and  will  void  your  product
warranty.

Figure 3 

Locate the snow blower hydraulic flow rating decal
(Item 1) 

[Figure 3]

 and ensure that the machine is

rated  for  the  required  flow.  Set  the  operator
controls  to  match  the  rated  flow  of  the  snow
blower. Do not operate at flow setting higher than
the  rated  flow.  Do  not  use  a  machine  that  is  not
rated for the required snow blower hydraulic flow.
