I know the side shift reel is leaking quite a bit. I've never had a forklift that wasn't at least 30 years old and leaking somewhere. If I remove the 2 reel lines at the diverter and cap them off do I have to "bleed" air of the system somehow? Wondering if this will help with the main cylinder. We rarely need the side shifter and when we do use it the truck stalls if we're not stepping on the throttle.
