frame with the capscrew and nut previously removed.
Tighten the top capscrew (Fig. 16).
9. To tension the counterbalance springs proceed as
follows:
A. Remove the cotter pin and clevis pin securing the
spring shackle to the counterbalance arm. Do not

Note: All configurations require calcium chloride in the
rear tire. Tires should be filled to approximately 75%
capacity (valve level with valve at the top) (60 lb. fluid or
74 lb. tire and fluid).
Important If a puncture occurs in a tire with calcium
chloride, remove the unit from the turf area as quickly as
possible. To prevent possible damage to the turf,
immediately soak the affected area with water.
Either Type 1 (77%) or Type 2 (94%) commercial calcium
chloride flake may be used.
Plain water freezes solid at 32°F (0°C). The 3-1/2 lb.
(1.6 kg) calcium chloride to 1 gallon (3.8 l) of water
solution is slush free to –12°F (–24°C) and will freeze solid
at –52°F (–46°C). The 5 lb. (2.3 kg) per gallon (liter)
solution is slush free to –50° F (–45°C) and will freeze
solid at –62°F (–52°C).
