ArborSystems Wedgle Direct-Inject Tree Injection System maintenance kit is included with every purchase. It’s held in the carrying case so you have it with you at all times. You don’t need a lot – just O-rings and a replaceable check valve. And that means you can reduce your maintenance cost since very few parts are required. Less parts means less time to fix anything and you are back injecting trees very quickly. So, make sure you ask about maintenance when you are considering which tree injection system to purchase as it is important to know what happens after you buy the system and are in the field.
