Emission Control System Infor2. Emission Control System Information Source of Emissions The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic.
Emission Control System Information Replacement Parts The emission control systems on your Wacker engine were designed, built, and certified to conform with EPA and California emissions regulations. We recommend the use of genuine Wacker parts whenever you have maintenance done. These original-design replacement parts are manufactured to the same standards as the original parts, so you can be confident of their performance.
Emission Control System InforMETHANOL - (methyl or wood alcohol) 5% by volume. You may use gasoline containing up to 5% methanol by volume, as long as it contains cosolvents and corrosion inhibitors to protect the fuel system. Gasoline containing more than 5% methanol by volume may cause starting and/or performance problems. It may also damage metal, rubber, and plastic parts of your fuel system.

Description 4. Description 4.1 Applications 4.1.1 4.2 For breaking concrete and asphalt as well as rubble-laden ground, for demolishing concrete, masonry and similar building materials (undisturbed and frozen ground) etc., for ripping up roads and concrete, asphalt, tar as well as wood-block and stone paving, for cutting off clay, loam, turf and salts, for breaking compacted or tamped ground, for ramming in posts and earth rods.
Description 4.3 Transport to work site Conditions: ∗ Only use appropriate lifting gear with a minimum load-bearing capacity of 30 kg when transporting the Wacker equipment. ∗ Always switch off motor during transport! ∗ Tie down the Wacker equipment when transporting it on the loadcarrying surface of a transport vehicle. Note: Also refer to the specifications in safety instruction. 4.4 T00931GB Description of function 4.4.
Operation 5. Operation 5.1 Starting procedure 5.1.1 Attaching the tool ∗ Swing catch (9) at tool holder (11) outwards. ∗ Clean shank (10) and grease slightly. ∗ Insert tool as far as possible. ∗ Press catch (9) back against tool holder (11). Only use sharp tools! Only use tools with shank (10) in perfect conditions to avoid rebound blows. 5.2 Engine Fuel Standard: 2 cycle oil/gasoline mixing ration of 1:50 or alternatively 1:100.
Operation BESCHREIBUNG Engaging clutch Once the engine has warmed up push throttle to full position (downwards). Winter operation! Extremely low temperatures require 2-3 minutes warming up of the engine at idling speed. As a result of the low temperatures, grease will have stiffened in the system. To overcome the difficulties arising from this, warm up the engine and lift the machine several times, then put system into operation by quickly opening the throttle. 5.
Operation 5.5 Notes for correct working procedure 5.5.1 Set the petrol breaker with its tool against the material to be worked on and start work by pressing down throttle. 5.5.2 Make use of the weight of the petrol breaker when working. 5.5.3 The performance of the tool is not improved by applying great pressure against the material to be worked on. 5.5.4 A certain amount of pressure on the handles is necessary in order to avoid no-load strokes and to ensure easy and agreeable handling. 5.5.
