Here's the settings and what they do:
MaxAmmo = 7, //the amount of 'ammo' the chainsaw has.
HitInterval = 0.05, //time between attacks are registered
AttractDistance = 256, //distance that common infected are attracted in hammer units
DamageResistence = 1, //the damage multiplier for a survivor attacking with the chainsaw
ChainsawDamage = 35, //the damage the chainsaw does per hit
ShouldFastDeploy = 1, //should the faster deploy animation play after the first slow deploy
AllowRestart = 1, //should the chainsaw restart when it runs out of fuel instead of being dropped
ReloadToRestart = 0, //should the player be able to restart the chainsaw whenever they want by pressing the reload key
