The counterbalance springs transfer the weight frame (and blower head) against the subframe. This

arrangement allows the height adjustment lever to easily raise and lower the entire blower head. The push frame must be locked into position (using the lockout pin) before

the springs can be properly adjusted.

Once the counterbalance springs are adjusted, they are under tension. The lockout pin must be kept in the locked position until the entire snowblower is fully installed.
